The omit PID list was parsed even when -o was not specified. In that case, arg was left uninitialized, so passing it to strtok() resulted in undefined behavior and could lead to a segfault. Only parse omit PIDs when -o is set. Also fix the exit status to return 1 when no matching PID is found
ubase - suckless linux base utils ================================= ubase is a collection of tools similar in spirit to util-linux but much simpler. The complement of ubase is sbase[1] which mostly follows POSIX and provides all the portable tools. Together they are intended to form a base system similar to busybox but much smaller and suckless. Building -------- To build ubase, simply type make. You may have to fiddle with config.mk and config.h depending on your system. You can also build ubase-box, which generates a single binary containing all the required tools. You can then symlink the individual tools to ubase-box or run: make ubase-box-install. To run the tools for ubase-box directly use: ubase-box cmd [args] Ideally you will want to statically link ubase. We highly recommend using musl-libc[2]. ubase is known to compile with gcc, clang and tcc. [1] http://git.suckless.org/sbase/ [2] http://www.musl-libc.org/
