If you are on Solaris, you could use dtrace for this. Create a file exit.d as

Code:
#!/usr/sbin/dtrace -s

syscall::rexit:
/execname == "ls"/
{
    printf ("ls exited with exitcode %d\n", arg0);
}

This example catches the exit code of the ls command. When you run the script, you get some output like:

Code:
dtrace: script './exit.d' matched 2 probes
CPU     ID                    FUNCTION:NAME
  7 105722                      rexit:entry ls exited with exitcode 0
  3 105722                      rexit:entry ls exited with exitcode 2
  1 105722                      rexit:entry ls exited with exitcode 0

The script will run, until you stop it with Ctrl-C.
