If you only need it to work on Linux, you can just enumerate 
/proc/[1-9]*/exe or /proc/[1-9]*/cmdline.

Or you can add -ww to "ps" to avoid truncating the output.

Note that the /proc/*/exe report the actual executable. The command line
reported by "ps" (from /proc/*/cmdline) can be modified by the program, so
it doesn't necessarily reflect the program being run.
