Show custom exit status in systemctl

Question

I would like to show a custom message when someone runs systemctl status and the script has failed.

Systemd seems to have a few built in.

If I have a script that runs exit 200 systemctl status will out put (code=exited, status=200/CHDIR)

How can set the status with a custom message? I would like to be able to do exit 199 and have it show something like status=199/MY_CODE

If the answer appears correct, please mark it accepted. – Mark Stosberg Nov 18 '17 at 16:31 — Mark Stosberg, Nov 18 '17 at 16:31

I find no mentions in the systemd docs that custom exit codes are possible. If you are interested in creating your own, you could modify systemd, re-compile and re-install, but I wouldn't recommend that. You could see src/basic/exit-status.h in the systemd source try as a starting point.

So based on reading the source code, what the OP is asking is not possible. The exit code to string map is a hard-coded switch statement. https://github.com/systemd/systemd/blob/master/src/basic/exit-status.c – wbkang Nov 17 '17 at 22:49
