From 2350f520a6dd7e293c5505aaa0983853cdd41ee6 Mon Sep 17 00:00:00 2001 From: Hiltjo Posthuma <hiltjo@codemadness.org> Date: Thu, 31 Jul 2025 14:40:43 +0200 Subject: [PATCH 3/4] xargs.c: implement -p, -P and -0, add TODO for -L - Add option to read arguments separated by NUL (-0). Useful with find -print0 for example. - Add very useful parallel option (-P). POSIX vaguely mentions parallel operations, but this is commonly supported and very useful. For example OpenBSD xargs supports it since at least 2003. GNU xargs since at least 1996. - Add prompt option (-p), (POSIX). - Add a TODO for xargs -L (POSIX extension). - Documentation and man page improvements.

The following list of commands is taken from the toybox roadmap[0] and
|
|
has been stripped down accordingly. Commands that belong to ubase[1]
|
|
are not listed here as well as commands that fall outside the scope of
|
|
sbase such as vi and sh are also not listed here.

If you are looking for some work to do on sbase, another option is to
|
|
pick a utility from the list in the README which has missing flags or
|
|
features noted.
|
|
|
|
What also needs to be implemented is the capability of the tools to
|
|
handle data with NUL-bytes in it.
|
|
|
|
The return values of mdcheckline() in crypt.c need to be fixed (0 -> success,
|
|
1 -> error).
