Basic Installation
|
||||
==================
|
||||
|
||||
Briefly, the shell command './configure && make && make install'
|
||||
should configure, build, and install this package. The following
|
||||
more-detailed instructions are generic; see the 'README' file for
|
||||
instructions specific to this package. Some packages provide this
|
||||
'INSTALL' file but do not implement all of the features documented
|
||||
below. The lack of an optional feature in a given package is not
|
||||
necessarily a bug. More recommendations for GNU packages can be found
|
||||
in *note Makefile Conventions: (standards)Makefile Conventions.
|
||||
|
||||
The 'configure' shell script attempts to guess correct values for
|
||||
various system-dependent variables used during compilation. It uses
|
||||
those values to create a 'Makefile' in each directory of the package.
|
||||
It may also create one or more '.h' files containing system-dependent
|
||||
definitions. Finally, it creates a shell script 'config.status' that
|
||||
you can run in the future to recreate the current configuration, and a
|
||||
file 'config.log' containing compiler output (useful mainly for
|
||||
debugging 'configure').
|
||||
|
||||
It can also use an optional file (typically called 'config.cache' and
|
||||
enabled with '--cache-file=config.cache' or simply '-C') that saves the
|
||||
results of its tests to speed up reconfiguring. Caching is disabled by
|
||||
default to prevent problems with accidental use of stale cache files.
|
||||
|
||||
If you need to do unusual things to compile the package, please try
|
||||
to figure out how 'configure' could check whether to do them, and mail
|
||||
diffs or instructions to the address given in the 'README' so they can
|
||||
be considered for the next release. If you are using the cache, and at
|
||||
some point 'config.cache' contains results you don't want to keep, you
|
||||
may remove or edit it.
|
||||
|
||||
The file 'configure.ac' (or 'configure.in') is used to create
|
||||
'configure' by a program called 'autoconf'. You need 'configure.ac' if
|
||||
you want to change it or regenerate 'configure' using a newer version of
|
||||
'autoconf'.
|
||||
|
||||
The simplest way to compile this package is:
|
||||
|
||||
1. 'cd' to the directory containing the package's source code and type
|
||||
'./configure' to configure the package for your system.
|
||||
|
||||
Running 'configure' might take a while. While running, it prints
|
||||
some messages telling which features it is checking for.
|
||||
|
||||
2. Type 'make' to compile the package.
|
||||
|
||||
3. Optionally, type 'make check' to run any self-tests that come with
|
||||
the package, generally using the just-built uninstalled binaries.
|
||||
|
||||
4. Type 'make install' to install the programs and any data files and
|
||||
documentation. When installing into a prefix owned by root, it is
|
||||
recommended that the package be configured and built as a regular
|
||||
user, and only the 'make install' phase executed with root
|
||||
privileges.
|
||||
|
||||
5. Optionally, type 'make installcheck' to repeat any self-tests, but
|
||||
this time using the binaries in their final installed location.
|
||||
This target does not install anything. Running this target as a
|
||||
regular user, particularly if the prior 'make install' required
|
||||
root privileges, verifies that the installation completed
|
||||
correctly.
|
||||
|
||||
6. You can remove the program binaries and object files from the
|
||||
source code directory by typing 'make clean'. To also remove the
|
||||
files that 'configure' created (so you can compile the package for
|
||||
a different kind of computer), type 'make distclean'. There is
|
||||
also a 'make maintainer-clean' target, but that is intended mainly
|
||||
for the package's developers. If you use it, you may have to get
|
||||
all sorts of other programs in order to regenerate files that came
|
||||
with the distribution.
|
||||
|
||||
7. Often, you can also type 'make uninstall' to remove the installed
|
||||
files again. In practice, not all packages have tested that
|
||||
uninstallation works correctly, even though it is required by the
|
||||
GNU Coding Standards.
|
||||
|
||||
8. Some packages, particularly those that use Automake, provide 'make
|
||||
distcheck', which can by used by developers to test that all other
|
||||
targets like 'make install' and 'make uninstall' work correctly.
|
||||
This target is generally not run by end users.
|
||||
|
||||
Compilers and Options
|
||||
=====================
|
||||
|
||||
Some systems require unusual options for compilation or linking that
|
||||
the 'configure' script does not know about. Run './configure --help'
|
||||
for details on some of the pertinent environment variables.
|
||||
|
||||
You can give 'configure' initial values for configuration parameters
|
||||
by setting variables in the command line or in the environment. Here is
|
||||
an example:
|
||||
|
||||
./configure CC=c99 CFLAGS=-g LIBS=-lposix
|
||||
|
||||
*Note Defining Variables::, for more details.
|
||||
|
||||
Compiling For Multiple Architectures
|
||||
====================================
|
||||
|
||||
You can compile the package for more than one kind of computer at the
|
||||
same time, by placing the object files for each architecture in their
|
||||
own directory. To do this, you can use GNU 'make'. 'cd' to the
|
||||
directory where you want the object files and executables to go and run
|
||||
the 'configure' script. 'configure' automatically checks for the source
|
||||
code in the directory that 'configure' is in and in '..'. This is known
|
||||
as a "VPATH" build.
|
||||
|
||||
With a non-GNU 'make', it is safer to compile the package for one
|
||||
architecture at a time in the source code directory. After you have
|
||||
installed the package for one architecture, use 'make distclean' before
|
||||
reconfiguring for another architecture.
|
||||
|
||||
On MacOS X 10.5 and later systems, you can create libraries and
|
||||
executables that work on multiple system types--known as "fat" or
|
||||
"universal" binaries--by specifying multiple '-arch' options to the
|
||||
compiler but only a single '-arch' option to the preprocessor. Like
|
||||
this:
|
||||
|
||||
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
|
||||
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
|
||||
CPP="gcc -E" CXXCPP="g++ -E"
|
||||
|
||||
This is not guaranteed to produce working output in all cases, you
|
||||
may have to build one architecture at a time and combine the results
|
||||
using the 'lipo' tool if you have problems.
|
||||
|
||||
Installation Names
|
||||
==================
|
||||
|
||||
By default, 'make install' installs the package's commands under
|
||||
'/usr/local/bin', include files under '/usr/local/include', etc. You
|
||||
can specify an installation prefix other than '/usr/local' by giving
|
||||
'configure' the option '--prefix=PREFIX', where PREFIX must be an
|
||||
absolute file name.
|
||||
|
||||
You can specify separate installation prefixes for
|
||||
architecture-specific files and architecture-independent files. If you
|
||||
pass the option '--exec-prefix=PREFIX' to 'configure', the package uses
|
||||
PREFIX as the prefix for installing programs and libraries.
|
||||
Documentation and other data files still use the regular prefix.
|
||||
|
||||
In addition, if you use an unusual directory layout you can give
|
||||
options like '--bindir=DIR' to specify different values for particular
|
||||
kinds of files. Run 'configure --help' for a list of the directories
|
||||
you can set and what kinds of files go in them. In general, the default
|
||||
for these options is expressed in terms of '${prefix}', so that
|
||||
specifying just '--prefix' will affect all of the other directory
|
||||
specifications that were not explicitly provided.
|
||||
|
||||
The most portable way to affect installation locations is to pass the
|
||||
correct locations to 'configure'; however, many packages provide one or
|
||||
both of the following shortcuts of passing variable assignments to the
|
||||
'make install' command line to change installation locations without
|
||||
having to reconfigure or recompile.
|
||||
|
||||
The first method involves providing an override variable for each
|
||||
affected directory. For example, 'make install
|
||||
prefix=/alternate/directory' will choose an alternate location for all
|
||||
directory configuration variables that were expressed in terms of
|
||||
'${prefix}'. Any directories that were specified during 'configure',
|
||||
but not in terms of '${prefix}', must each be overridden at install time
|
||||
for the entire installation to be relocated. The approach of makefile
|
||||
variable overrides for each directory variable is required by the GNU
|
||||
Coding Standards, and ideally causes no recompilation. However, some
|
||||
platforms have known limitations with the semantics of shared libraries
|
||||
that end up requiring recompilation when using this method, particularly
|
||||
noticeable in packages that use GNU Libtool.
|
||||
|
||||
The second method involves providing the 'DESTDIR' variable. For
|
||||
example, 'make install DESTDIR=/alternate/directory' will prepend
|
||||
'/alternate/directory' before all installation names. The approach of
|
||||
'DESTDIR' overrides is not required by the GNU Coding Standards, and
|
||||
does not work on platforms that have drive letters. On the other hand,
|
||||
it does better at avoiding recompilation issues, and works well even
|
||||
when some directory options were not specified in terms of '${prefix}'
|
||||
at 'configure' time.
|
||||
|
||||
Optional Features
|
||||
=================
|
||||
|
||||
If the package supports it, you can cause programs to be installed
|
||||
with an extra prefix or suffix on their names by giving 'configure' the
|
||||
option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'.
|
||||
|
||||
Some packages pay attention to '--enable-FEATURE' options to
|
||||
'configure', where FEATURE indicates an optional part of the package.
|
||||
They may also pay attention to '--with-PACKAGE' options, where PACKAGE
|
||||
is something like 'gnu-as' or 'x' (for the X Window System). The
|
||||
'README' should mention any '--enable-' and '--with-' options that the
|
||||
package recognizes.
|
||||
|
||||
For packages that use the X Window System, 'configure' can usually
|
||||
find the X include and library files automatically, but if it doesn't,
|
||||
you can use the 'configure' options '--x-includes=DIR' and
|
||||
'--x-libraries=DIR' to specify their locations.
|
||||
|
||||
Some packages offer the ability to configure how verbose the
|
||||
execution of 'make' will be. For these packages, running './configure
|
||||
--enable-silent-rules' sets the default to minimal output, which can be
|
||||
overridden with 'make V=1'; while running './configure
|
||||
--disable-silent-rules' sets the default to verbose, which can be
|
||||
overridden with 'make V=0'.
|
||||
|
||||
Particular systems
|
||||
==================
|
||||
|
||||
On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC
|
||||
is not installed, it is recommended to use the following options in
|
||||
order to use an ANSI C compiler:
|
||||
|
||||
./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
|
||||
|
||||
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
|
||||
|
||||
HP-UX 'make' updates targets which have the same time stamps as their
|
||||
prerequisites, which makes it generally unusable when shipped generated
|
||||
files such as 'configure' are involved. Use GNU 'make' instead.
|
||||
|
||||
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
|
||||
parse its '<wchar.h>' header file. The option '-nodtk' can be used as a
|
||||
workaround. If GNU CC is not installed, it is therefore recommended to
|
||||
try
|
||||
|
||||
./configure CC="cc"
|
||||
|
||||
and if that doesn't work, try
|
||||
|
||||
./configure CC="cc -nodtk"
|
||||
|
||||
On Solaris, don't put '/usr/ucb' early in your 'PATH'. This
|
||||
directory contains several dysfunctional programs; working variants of
|
||||
these programs are available in '/usr/bin'. So, if you need '/usr/ucb'
|
||||
in your 'PATH', put it _after_ '/usr/bin'.
|
||||
|
||||
On Haiku, software installed for all users goes in '/boot/common',
|
||||
not '/usr/local'. It is recommended to use the following options:
|
||||
|
||||
./configure --prefix=/boot/common
|
||||
|
||||
Specifying the System Type
|
||||
==========================
|
||||
|
||||
There may be some features 'configure' cannot figure out
|
||||
automatically, but needs to determine by the type of machine the package
|
||||
will run on. Usually, assuming the package is built to be run on the
|
||||
_same_ architectures, 'configure' can figure that out, but if it prints
|
||||
a message saying it cannot guess the machine type, give it the
|
||||
'--build=TYPE' option. TYPE can either be a short name for the system
|
||||
type, such as 'sun4', or a canonical name which has the form:
|
||||
|
||||
CPU-COMPANY-SYSTEM
|
||||
|
||||
where SYSTEM can have one of these forms:
|
||||
|
||||
OS
|
||||
KERNEL-OS
|
||||
|
||||
See the file 'config.sub' for the possible values of each field. If
|
||||
'config.sub' isn't included in this package, then this package doesn't
|
||||
need to know the machine type.
|
||||
|
||||
If you are _building_ compiler tools for cross-compiling, you should
|
||||
use the option '--target=TYPE' to select the type of system they will
|
||||
produce code for.
|
||||
|
||||
If you want to _use_ a cross compiler, that generates code for a
|
||||
platform different from the build platform, you should specify the
|
||||
"host" platform (i.e., that on which the generated programs will
|
||||
eventually be run) with '--host=TYPE'.
|
||||
|
||||
Sharing Defaults
|
||||
================
|
||||
|
||||
If you want to set default values for 'configure' scripts to share,
|
||||
you can create a site shell script called 'config.site' that gives
|
||||
default values for variables like 'CC', 'cache_file', and 'prefix'.
|
||||
'configure' looks for 'PREFIX/share/config.site' if it exists, then
|
||||
'PREFIX/etc/config.site' if it exists. Or, you can set the
|
||||
'CONFIG_SITE' environment variable to the location of the site script.
|
||||
A warning: not all 'configure' scripts look for a site script.
|
||||
|
||||
Defining Variables
|
||||
==================
|
||||
|
||||
Variables not defined in a site shell script can be set in the
|
||||
environment passed to 'configure'. However, some packages may run
|
||||
configure again during the build, and the customized values of these
|
||||
variables may be lost. In order to avoid this problem, you should set
|
||||
them in the 'configure' command line, using 'VAR=value'. For example:
|
||||
|
||||
./configure CC=/usr/local2/bin/gcc
|
||||
|
||||
causes the specified 'gcc' to be used as the C compiler (unless it is
|
||||
overridden in the site shell script).
|
||||
|
||||
Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an
|
||||
Autoconf limitation. Until the limitation is lifted, you can use this
|
||||
workaround:
|
||||
|
||||
CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
|
||||
|
||||
'configure' Invocation
|
||||
======================
|
||||
|
||||
'configure' recognizes the following options to control how it
|
||||
operates.
|
||||
|
||||
'--help'
|
||||
'-h'
|
||||
Print a summary of all of the options to 'configure', and exit.
|
||||
|
||||
'--help=short'
|
||||
'--help=recursive'
|
||||
Print a summary of the options unique to this package's
|
||||
'configure', and exit. The 'short' variant lists options used only
|
||||
in the top level, while the 'recursive' variant lists options also
|
||||
present in any nested packages.
|
||||
|
||||
'--version'
|
||||
'-V'
|
||||
Print the version of Autoconf used to generate the 'configure'
|
||||
script, and exit.
|
||||
|
||||
'--cache-file=FILE'
|
||||
Enable the cache: use and save the results of the tests in FILE,
|
||||
traditionally 'config.cache'. FILE defaults to '/dev/null' to
|
||||
disable caching.
|
||||
|
||||
'--config-cache'
|
||||
'-C'
|
||||
Alias for '--cache-file=config.cache'.
|
||||
|
||||
'--quiet'
|
||||
'--silent'
|
||||
'-q'
|
||||
Do not print messages saying which checks are being made. To
|
||||
suppress all normal output, redirect it to '/dev/null' (any error
|
||||
messages will still be shown).
|
||||
|
||||
'--srcdir=DIR'
|
||||
Look for the package's source code in directory DIR. Usually
|
||||
'configure' can determine that directory automatically.
|
||||
|
||||
'--prefix=DIR'
|
||||
Use DIR as the installation prefix. *note Installation Names:: for
|
||||
more details, including other options available for fine-tuning the
|
||||
installation locations.
|
||||
|
||||
'--no-create'
|
||||
'-n'
|
||||
Run the configure checks, but stop before creating any output
|
||||
files.
|
||||
|
||||
'configure' also accepts some other, not widely useful, options. Run
|
||||
'configure --help' for more details.

|

## This next piece of magic avoids the "deleted header file" problem.

## The problem is that when a header file which appears in a .P file

## dummy dependencies for each header file. Too bad gcc doesn't do

## that the space means something, we add a space to the output as

NOTE -- This is the original TOUR paper distributed with ash and
|
||||
does not represent the current state of the shell. It is provided anyway
|
||||
since it provides helpful information for how the shell is structured,
|
||||
but be warned that things have changed -- the current shell is
|
||||
still under development.

A Tour through Ash
|
||||
|
||||
Copyright 1989 by Kenneth Almquist.
|
||||
|
||||
|
||||
DIRECTORIES: The subdirectory bltin contains commands which can
|
||||
be compiled stand-alone. The rest of the source is in the main
|
||||
ash directory.
|
||||
|
||||
SOURCE CODE GENERATORS: Files whose names begin with "mk" are
|
||||
programs that generate source code. A complete list of these
|
||||
programs is:
|
||||
|
||||
program intput files generates
|
||||
------- ------------ ---------
|
||||
mkbuiltins builtins builtins.h builtins.c
|
||||
mkinit *.c init.c
|
||||
mknodes nodetypes nodes.h nodes.c
|
||||
mksignames - signames.h signames.c
|
||||
mksyntax - syntax.h syntax.c
|
||||
mktokens - token.h
|
||||
bltin/mkexpr unary_op binary_op operators.h operators.c
|
||||
|
||||
There are undoubtedly too many of these. Mkinit searches all the
|
||||
C source files for entries looking like:
|
||||
|
||||
INIT {
|
||||
x = 1; /* executed during initialization */
|
||||
}
|
||||
|
||||
RESET {
|
||||
x = 2; /* executed when the shell does a longjmp
|
||||
back to the main command loop */
|
||||
}
|
||||
|
||||
It pulls this code out into routines which are when particular
|
||||
events occur. The intent is to improve modularity by isolating
|
||||
the information about which modules need to be explicitly
|
||||
initialized/reset within the modules themselves.
|
||||
|
||||
Mkinit recognizes several constructs for placing declarations in
|
||||
the init.c file.
|
||||
INCLUDE "file.h"
|
||||
includes a file. The storage class MKINIT makes a declaration
|
||||
available in the init.c file, for example:
|
||||
MKINIT int funcnest; /* depth of function calls */
|
||||
MKINIT alone on a line introduces a structure or union declara-
|
||||
tion:
|
||||
MKINIT
|
||||
struct redirtab {
|
||||
short renamed[10];
|
||||
};
|
||||
Preprocessor #define statements are copied to init.c without any
|
||||
special action to request this.
|
||||
|
||||
INDENTATION: The ash source is indented in multiples of six
|
||||
spaces. The only study that I have heard of on the subject con-
|
||||
cluded that the optimal amount to indent is in the range of four
|
||||
to six spaces. I use six spaces since it is not too big a jump
|
||||
from the widely used eight spaces. If you really hate six space
|
||||
indentation, use the adjind (source included) program to change
|
||||
it to something else.
|
||||
|
||||
EXCEPTIONS: Code for dealing with exceptions appears in
|
||||
exceptions.c. The C language doesn't include exception handling,
|
||||
so I implement it using setjmp and longjmp. The global variable
|
||||
exception contains the type of exception. EXERROR is raised by
|
||||
calling error. EXINT is an interrupt.
|
||||
|
||||
INTERRUPTS: In an interactive shell, an interrupt will cause an
|
||||
EXINT exception to return to the main command loop. (Exception:
|
||||
EXINT is not raised if the user traps interrupts using the trap
|
||||
command.) The INTOFF and INTON macros (defined in exception.h)
|
||||
provide uninterruptable critical sections. Between the execution
|
||||
of INTOFF and the execution of INTON, interrupt signals will be
|
||||
held for later delivery. INTOFF and INTON can be nested.
|
||||
|
||||
MEMALLOC.C: Memalloc.c defines versions of malloc and realloc
|
||||
which call error when there is no memory left. It also defines a
|
||||
stack oriented memory allocation scheme. Allocating off a stack
|
||||
is probably more efficient than allocation using malloc, but the
|
||||
big advantage is that when an exception occurs all we have to do
|
||||
to free up the memory in use at the time of the exception is to
|
||||
restore the stack pointer. The stack is implemented using a
|
||||
linked list of blocks.
|
||||
|
||||
STPUTC: If the stack were contiguous, it would be easy to store
|
||||
strings on the stack without knowing in advance how long the
|
||||
string was going to be:
|
||||
p = stackptr;
|
||||
*p++ = c; /* repeated as many times as needed */
|
||||
stackptr = p;
|
||||
The following three macros (defined in memalloc.h) perform these
|
||||
operations, but grow the stack if you run off the end:
|
||||
STARTSTACKSTR(p);
|
||||
STPUTC(c, p); /* repeated as many times as needed */
|
||||
grabstackstr(p);
|
||||
|
||||
We now start a top-down look at the code:
|
||||
|
||||
MAIN.C: The main routine performs some initialization, executes
|
||||
the user's profile if necessary, and calls cmdloop. Cmdloop is
|
||||
repeatedly parses and executes commands.
|
||||
|
||||
OPTIONS.C: This file contains the option processing code. It is
|
||||
called from main to parse the shell arguments when the shell is
|
||||
invoked, and it also contains the set builtin. The -i and -j op-
|
||||
tions (the latter turns on job control) require changes in signal
|
||||
handling. The routines setjobctl (in jobs.c) and setinteractive
|
||||
(in trap.c) are called to handle changes to these options.
|
||||
|
||||
PARSING: The parser code is all in parser.c. A recursive des-
|
||||
cent parser is used. Syntax tables (generated by mksyntax) are
|
||||
used to classify characters during lexical analysis. There are
|
||||
three tables: one for normal use, one for use when inside single
|
||||
quotes, and one for use when inside double quotes. The tables
|
||||
are machine dependent because they are indexed by character vari-
|
||||
ables and the range of a char varies from machine to machine.
|
||||
|
||||
PARSE OUTPUT: The output of the parser consists of a tree of
|
||||
nodes. The various types of nodes are defined in the file node-
|
||||
types.
|
||||
|
||||
Nodes of type NARG are used to represent both words and the con-
|
||||
tents of here documents. An early version of ash kept the con-
|
||||
tents of here documents in temporary files, but keeping here do-
|
||||
cuments in memory typically results in significantly better per-
|
||||
formance. It would have been nice to make it an option to use
|
||||
temporary files for here documents, for the benefit of small
|
||||
machines, but the code to keep track of when to delete the tem-
|
||||
porary files was complex and I never fixed all the bugs in it.
|
||||
(AT&T has been maintaining the Bourne shell for more than ten
|
||||
years, and to the best of my knowledge they still haven't gotten
|
||||
it to handle temporary files correctly in obscure cases.)
|
||||
|
||||
The text field of a NARG structure points to the text of the
|
||||
word. The text consists of ordinary characters and a number of
|
||||
special codes defined in parser.h. The special codes are:
|
||||
|
||||
CTLVAR Variable substitution
|
||||
CTLENDVAR End of variable substitution
|
||||
CTLBACKQ Command substitution
|
||||
CTLESC Escape next character
|
||||
|
||||
A variable substitution contains the following elements:
|
||||
|
||||
CTLVAR type name '=' [ alternative-text CTLENDVAR ]
|
||||
|
||||
The type field is a single character specifying the type of sub-
|
||||
stitution. The possible types are:
|
||||
|
||||
VSNORMAL $var
|
||||
VSMINUS ${var-text}
|
||||
VSMINUS|VSNUL ${var:-text}
|
||||
VSPLUS ${var+text}
|
||||
VSPLUS|VSNUL ${var:+text}
|
||||
VSQUESTION ${var?text}
|
||||
VSQUESTION|VSNUL ${var:?text}
|
||||
VSASSIGN ${var=text}
|
||||
VSASSIGN|VSNUL ${var=text}
|
||||
|
||||
The name of the variable comes next, terminated by an equals
|
||||
sign. If the type is not VSNORMAL, then the text field in the
|
||||
substitution follows, terminated by a CTLENDVAR byte.
|
||||
|
||||
Commands in back quotes are parsed and stored in a linked list.
|
||||
The locations of these commands in the string are indicated by
|
||||
the CTLBACKQ character.
|
||||
|
||||
The character CTLESC escapes the next character, so that in case
|
||||
any of the CTL characters mentioned above appear in the input,
|
||||
they can be passed through transparently. CTLESC is also used to
|
||||
escape '*', '?', '[', and '!' characters which were quoted by the
|
||||
user and thus should not be used for file name generation.
|
||||
|
||||
CTLESC characters have proved to be particularly tricky to get
|
||||
right. In the case of here documents which are not subject to
|
||||
variable and command substitution, the parser doesn't insert any
|
||||
CTLESC characters to begin with (so the contents of the text
|
||||
field can be written without any processing). Other here docu-
|
||||
ments, and words which are not subject to splitting and file name
|
||||
generation, have the CTLESC characters removed during the vari-
|
||||
able and command substitution phase. Words which are subject
|
||||
splitting and file name generation have the CTLESC characters re-
|
||||
moved as part of the file name phase.
|
||||
|
||||
EXECUTION: Command execution is handled by the following files:
|
||||
eval.c The top level routines.
|
||||
redir.c Code to handle redirection of input and output.
|
||||
jobs.c Code to handle forking, waiting, and job control.
|
||||
exec.c Code to path searches and the actual exec sys call.
|
||||
expand.c Code to evaluate arguments.
|
||||
var.c Maintains the variable symbol table. Called from expand.c.
|
||||
|
||||
EVAL.C: Evaltree recursively executes a parse tree. The exit
|
||||
status is returned in the global variable exitstatus. The alter-
|
||||
native entry evalbackcmd is called to evaluate commands in back
|
||||
quotes. It saves the result in memory if the command is a buil-
|
||||
tin; otherwise it forks off a child to execute the command and
|
||||
connects the standard output of the child to a pipe.
|
||||
|
||||
JOBS.C: To create a process, you call makejob to return a job
|
||||
structure, and then call forkshell (passing the job structure as
|
||||
an argument) to create the process. Waitforjob waits for a job
|
||||
to complete. These routines take care of process groups if job
|
||||
control is defined.
|
||||
|
||||
REDIR.C: Ash allows file descriptors to be redirected and then
|
||||
restored without forking off a child process. This is accom-
|
||||
plished by duplicating the original file descriptors. The redir-
|
||||
tab structure records where the file descriptors have be dupli-
|
||||
cated to.
|
||||
|
||||
EXEC.C: The routine find_command locates a command, and enters
|
||||
the command in the hash table if it is not already there. The
|
||||
third argument specifies whether it is to print an error message
|
||||
if the command is not found. (When a pipeline is set up,
|
||||
find_command is called for all the commands in the pipeline be-
|
||||
fore any forking is done, so to get the commands into the hash
|
||||
table of the parent process. But to make command hashing as
|
||||
transparent as possible, we silently ignore errors at that point
|
||||
and only print error messages if the command cannot be found
|
||||
later.)
|
||||
|
||||
The routine shellexec is the interface to the exec system call.
|
||||
|
||||
EXPAND.C: Arguments are processed in three passes. The first
|
||||
(performed by the routine argstr) performs variable and command
|
||||
substitution. The second (ifsbreakup) performs word splitting
|
||||
and the third (expandmeta) performs file name generation. If the
|
||||
"/u" directory is simulated, then when "/u/username" is replaced
|
||||
by the user's home directory, the flag "didudir" is set. This
|
||||
tells the cd command that it should print out the directory name,
|
||||
just as it would if the "/u" directory were implemented using
|
||||
symbolic links.
|
||||
|
||||
VAR.C: Variables are stored in a hash table. Probably we should
|
||||
switch to extensible hashing. The variable name is stored in the
|
||||
same string as the value (using the format "name=value") so that
|
||||
no string copying is needed to create the environment of a com-
|
||||
mand. Variables which the shell references internally are preal-
|
||||
located so that the shell can reference the values of these vari-
|
||||
ables without doing a lookup.
|
||||
|
||||
When a program is run, the code in eval.c sticks any environment
|
||||
variables which precede the command (as in "PATH=xxx command") in
|
||||
the variable table as the simplest way to strip duplicates, and
|
||||
then calls "environment" to get the value of the environment.
|
||||
There are two consequences of this. First, if an assignment to
|
||||
PATH precedes the command, the value of PATH before the assign-
|
||||
ment must be remembered and passed to shellexec. Second, if the
|
||||
program turns out to be a shell procedure, the strings from the
|
||||
environment variables which preceded the command must be pulled
|
||||
out of the table and replaced with strings obtained from malloc,
|
||||
since the former will automatically be freed when the stack (see
|
||||
the entry on memalloc.c) is emptied.
|
||||
|
||||
BUILTIN COMMANDS: The procedures for handling these are scat-
|
||||
tered throughout the code, depending on which location appears
|
||||
most appropriate. They can be recognized because their names al-
|
||||
ways end in "cmd". The mapping from names to procedures is
|
||||
specified in the file builtins, which is processed by the mkbuil-
|
||||
tins command.
|
||||
|
||||
A builtin command is invoked with argc and argv set up like a
|
||||
normal program. A builtin command is allowed to overwrite its
|
||||
arguments. Builtin routines can call nextopt to do option pars-
|
||||
ing. This is kind of like getopt, but you don't pass argc and
|
||||
argv to it. Builtin routines can also call error. This routine
|
||||
normally terminates the shell (or returns to the main command
|
||||
loop if the shell is interactive), but when called from a builtin
|
||||
command it causes the builtin command to terminate with an exit
|
||||
status of 2.
|
||||
|
||||
The directory bltins contains commands which can be compiled in-
|
||||
dependently but can also be built into the shell for efficiency
|
||||
reasons. The makefile in this directory compiles these programs
|
||||
in the normal fashion (so that they can be run regardless of
|
||||
whether the invoker is ash), but also creates a library named
|
||||
bltinlib.a which can be linked with ash. The header file bltin.h
|
||||
takes care of most of the differences between the ash and the
|
||||
stand-alone environment. The user should call the main routine
|
||||
"main", and #define main to be the name of the routine to use
|
||||
when the program is linked into ash. This #define should appear
|
||||
before bltin.h is included; bltin.h will #undef main if the pro-
|
||||
gram is to be compiled stand-alone.
|
||||
|
||||
CD.C: This file defines the cd and pwd builtins. The pwd com-
|
||||
mand runs /bin/pwd the first time it is invoked (unless the user
|
||||
has already done a cd to an absolute pathname), but then
|
||||
remembers the current directory and updates it when the cd com-
|
||||
mand is run, so subsequent pwd commands run very fast. The main
|
||||
complication in the cd command is in the docd command, which
|
||||
resolves symbolic links into actual names and informs the user
|
||||
where the user ended up if he crossed a symbolic link.
|
||||
|
||||
SIGNALS: Trap.c implements the trap command. The routine set-
|
||||
signal figures out what action should be taken when a signal is
|
||||
received and invokes the signal system call to set the signal ac-
|
||||
tion appropriately. When a signal that a user has set a trap for
|
||||
is caught, the routine "onsig" sets a flag. The routine dotrap
|
||||
is called at appropriate points to actually handle the signal.
|
||||
When an interrupt is caught and no trap has been set for that
|
||||
signal, the routine "onint" in error.c is called.
|
||||
|
||||
OUTPUT: Ash uses it's own output routines. There are three out-
|
||||
put structures allocated. "Output" represents the standard out-
|
||||
put, "errout" the standard error, and "memout" contains output
|
||||
which is to be stored in memory. This last is used when a buil-
|
||||
tin command appears in backquotes, to allow its output to be col-
|
||||
lected without doing any I/O through the UNIX operating system.
|
||||
The variables out1 and out2 normally point to output and errout,
|
||||
respectively, but they are set to point to memout when appropri-
|
||||
ate inside backquotes.
|
||||
|
||||
INPUT: The basic input routine is pgetc, which reads from the
|
||||
current input file. There is a stack of input files; the current
|
||||
input file is the top file on this stack. The code allows the
|
||||
input to come from a string rather than a file. (This is for the
|
||||
-c option and the "." and eval builtin commands.) The global
|
||||
variable plinno is saved and restored when files are pushed and
|
||||
popped from the stack. The parser routines store the number of
|
||||
the current line in this variable.
|
||||
|
||||
DEBUGGING: If DEBUG is defined in shell.h, then the shell will
|
||||
write debugging information to the file $HOME/trace. Most of
|
||||
this is done using the TRACE macro, which takes a set of printf
|
||||
arguments inside two sets of parenthesis. Example:
|
||||
"TRACE(("n=%d0, n))". The double parenthesis are necessary be-
|
||||
cause the preprocessor can't handle functions with a variable
|
||||
number of arguments. Defining DEBUG also causes the shell to
|
||||
generate a core dump if it is sent a quit signal. The tracing
|
||||
code is in show.c.

.Nm
|

|

.Sh DESCRIPTION
|
||||
.Nm
|
||||
prints its arguments on the standard output, separated by spaces.
|
||||
Unless the
|
||||
.Fl n
|
||||
option is present, a newline is output following the arguments.
|
||||
The
|
||||
.Fl e
|
||||
option causes
|
||||
.Nm
|
||||
to treat the escape sequences specially, as described in the following
|
||||
paragraph.
|
||||
The
|
||||
.Fl e
|
||||
option is the default, and is provided solely for compatibility with
|
||||
other systems.
|
||||
Only one of the options
|
||||
.Fl n
|
||||
and
|
||||
.Fl e
|
||||
may be given.
|
||||
.Pp
|
||||
If any of the following sequences of characters is encountered during
|
||||
output, the sequence is not output.
|
||||
Instead, the specified action is
|
||||
performed:
|
||||
.Bl -tag -width indent
|
||||
.It Li \eb
|
||||
A backspace character is output.
|
||||
.It Li \ec
|
||||
Subsequent output is suppressed.
|
||||
This is normally used at the end of the
|
||||
last argument to suppress the trailing newline that
|
||||
.Nm
|
||||
would otherwise output.
|
||||
.It Li \ef
|
||||
Output a form feed.
|
||||
.It Li \en
|
||||
Output a newline character.
|
||||
.It Li \er
|
||||
Output a carriage return.
|
||||
.It Li \et
|
||||
Output a (horizontal) tab character.
|
||||
.It Li \ev
|
||||
Output a vertical tab.
|
||||
.It Li \e0 Ns Ar digits
|
||||
Output the character whose value is given by zero to three digits.
|
||||
If there are zero digits, a nul character is output.
|
||||
.It Li \e\e
|
||||
Output a backslash.
|
||||
.El
|
||||
.Sh HINTS
|
||||
Remember that backslash is special to the shell and needs to be escaped.
|
||||
To output a message to standard error, say
|
||||
.Pp
|
||||
.D1 echo message \*[Gt]\*[Am]2
|
||||
.Sh BUGS
|
||||
The octal character escape mechanism
|
||||
.Pq Li \e0 Ns Ar digits
|
||||
differs from the
|
||||
C language mechanism.
|
||||
.Pp
|
||||
There is no way to force
|
||||
.Nm
|
||||
to treat its arguments literally, rather than interpreting them as
|
||||
options and escape sequences.

.Sh DESCRIPTION
|
||||
.Nm
|
||||
formats and prints its arguments, after the first, under control
|
||||
of the
|
||||
.Ar format .
|
||||
The
|
||||
.Ar format
|
||||
is a character string which contains three types of objects: plain characters,
|
||||
which are simply copied to standard output, character escape sequences which
|
||||
are converted and copied to the standard output, and format specifications,
|
||||
each of which causes printing of the next successive
|
||||
.Ar argument .
|
||||
.Pp
|
||||
The
|
||||
.Ar arguments
|
||||
after the first are treated as strings if the corresponding format is
|
||||
either
|
||||
.Cm b ,
|
||||
.Cm B ,
|
||||
.Cm c
|
||||
or
|
||||
.Cm s ;
|
||||
otherwise it is evaluated as a C constant, with the following extensions:
|
||||
.Pp
|
||||
.Bl -bullet -offset indent -compact
|
||||
.It
|
||||
A leading plus or minus sign is allowed.
|
||||
.It
|
||||
If the leading character is a single or double quote, the value is the
|
||||
.Tn ASCII
|
||||
code of the next character.
|
||||
.El
|
||||
.Pp
|
||||
The format string is reused as often as necessary to satisfy the
|
||||
.Ar arguments .
|
||||
Any extra format specifications are evaluated with zero or the null
|
||||
string.
|
||||
.Pp
|
||||
Character escape sequences are in backslash notation as defined in
|
||||
.St -ansiC .
|
||||
The characters and their meanings are as follows:
|
||||
.Bl -tag -width Ds -offset indent
|
||||
.It Cm \ee
|
||||
Write an \*[Lt]escape\*[Gt] character.
|
||||
.It Cm \ea
|
||||
Write a \*[Lt]bell\*[Gt] character.
|
||||
.It Cm \eb
|
||||
Write a \*[Lt]backspace\*[Gt] character.
|
||||
.It Cm \ef
|
||||
Write a \*[Lt]form-feed\*[Gt] character.
|
||||
.It Cm \en
|
||||
Write a \*[Lt]new-line\*[Gt] character.
|
||||
.It Cm \er
|
||||
Write a \*[Lt]carriage return\*[Gt] character.
|
||||
.It Cm \et
|
||||
Write a \*[Lt]tab\*[Gt] character.
|
||||
.It Cm \ev
|
||||
Write a \*[Lt]vertical tab\*[Gt] character.
|
||||
.It Cm \e\'
|
||||
Write a \*[Lt]single quote\*[Gt] character.
|
||||
.It Cm \e"
|
||||
Write a \*[Lt]double quote\*[Gt] character.
|
||||
.It Cm \e\e
|
||||
Write a backslash character.
|
||||
.It Cm \e Ns Ar num
|
||||
Write an 8\-bit character whose
|
||||
.Tn ASCII
|
||||
value is the 1\-, 2\-, or 3\-digit octal number
|
||||
.Ar num .
|
||||
.It Cm \ex Ns Ar xx
|
||||
Write an 8\-bit character whose
|
||||
.Tn ASCII
|
||||
value is the 1\- or 2\-digit hexadecimal number
|
||||
.Ar xx .
|
||||
.El
|
||||
.Pp
|
||||
Each format specification is introduced by the percent character
|
||||
(``%'').
|
||||
The remainder of the format specification includes,
|
||||
in the following order:
|
||||
.Bl -tag -width Ds
|
||||
.It "Zero or more of the following flags:"
|
||||
.Bl -tag -width Ds
|
||||
.It Cm #
|
||||
A `#' character
|
||||
specifying that the value should be printed in an ``alternative form''.
|
||||
For
|
||||
.Cm b ,
|
||||
.Cm c ,
|
||||
.Cm d ,
|
||||
and
|
||||
.Cm s
|
||||
formats, this option has no effect.
|
||||
For the
|
||||
.Cm o
|
||||
format the precision of the number is increased to force the first
|
||||
character of the output string to a zero.
|
||||
For the
|
||||
.Cm x
|
||||
.Pq Cm X
|
||||
format, a non-zero result has the string
|
||||
.Li 0x
|
||||
.Pq Li 0X
|
||||
prepended to it.
|
||||
For
|
||||
.Cm e ,
|
||||
.Cm E ,
|
||||
.Cm f ,
|
||||
.Cm g ,
|
||||
and
|
||||
.Cm G
|
||||
formats, the result will always contain a decimal point, even if no
|
||||
digits follow the point (normally, a decimal point only appears in the
|
||||
results of those formats if a digit follows the decimal point).
|
||||
For
|
||||
.Cm g
|
||||
and
|
||||
.Cm G
|
||||
formats, trailing zeros are not removed from the result as they
|
||||
would otherwise be.

.\" I turned this off - decided it isn't a valid use of '#'
|

.\" For the
|
||||
.\" .Cm B
|

|

.It Cm \&\-
|

A minus sign `\-' which specifies

.Em left adjustment
|

of the output in the indicated field;
|

.It Cm \&+
|
||||
A `+' character specifying that there should always be

a sign placed before the number when using signed formats.
|
||||
.It Sq \&\ \&
|
||||
A space specifying that a blank should be left before a positive number
|
||||
for a signed format.
|
||||
A `+' overrides a space if both are used;
|
||||
.It Cm \&0
|
||||
A zero `0' character indicating that zero-padding should be used
|

rather than blank-padding.
|

A `\-' overrides a `0' if both are used;
|

.El
|

.It "Field Width:"
|

An optional digit string specifying a

if the output string has fewer characters than the field width it will

be blank-padded on the left (or right, if the left-adjustment indicator
|
||||
has been given) to make up the field width (note that a leading zero
|
||||
is a flag, but an embedded zero is part of a field width);
|

.It Precision :

An optional period,
|

.Sq Cm \&.\& ,
|

followed by an optional digit string giving a

|

which specifies the number of digits to appear after the decimal point,

|
||||
.Sh STANDARDS
|
||||
The
|
||||
.Nm
|
||||
utility conforms to
|
||||
.St -p1003.1-2001 .
|
||||
.Pp
|
||||
Support for the floating point formats and `*' as a field width and precision
|
||||
are optional in POSIX.
|
||||
.Pp
|
||||
The behaviour of the %B format and the \e', \e", \exxx, \ee and
|
||||
\e[M][\-|^]c escape sequences are undefined in POSIX.
|
||||
.Sh BUGS
|
||||
Since the floating point numbers are translated from
|
||||
.Tn ASCII
|
||||
to floating-point and
|
||||
then back again, floating-point precision may be lost.
|
||||
.Pp
|
||||
Hexadecimal character constants are restricted to, and should be specified
|
||||
as, two character constants.
|
||||
This is contrary to the ISO C standard but
|
||||
does guarantee detection of the end of the constant.

.Sh DESCRIPTION
|
||||
The
|
||||
.Nm test
|
||||
utility evaluates the expression and, if it evaluates
|
||||
to true, returns a zero (true) exit status; otherwise
|
||||
it returns 1 (false).
|
||||
If there is no expression, test also
|
||||
returns 1 (false).
|
||||
.Pp
|
||||
All operators and flags are separate arguments to the
|
||||
.Nm test
|
||||
utility.
|
||||
.Pp
|

.Sh GRAMMAR AMBIGUITY
|
||||
The
|
||||
.Nm test
|
||||
grammar is inherently ambiguous.
|
||||
In order to assure a degree of consistency, the cases described in
|
||||
.St -p1003.2
|
||||
section 4.62.4,
|
||||
are evaluated consistently according to the rules specified in the
|
||||
standards document.
|
||||
All other cases are subject to the ambiguity in the command semantics.
|
||||
.Sh EXIT STATUS
|
||||
The
|
||||
.Nm test
|
||||
utility exits with one of the following values:
|
||||
.Bl -tag -width Ds
|
||||
.It 0
|
||||
expression evaluated to true.
|
||||
.It 1
|
||||
expression evaluated to false or expression was
|
||||
missing.
|
||||
.It \*[Gt]1
|
||||
An error occurred.
|
||||
.El
|
||||
.Sh STANDARDS
|
||||
The
|
||||
.Nm test
|
||||
utility implements a superset of the
|
||||
.St -p1003.2
|
||||
specification.
