Hi Everyone, I have a script that fully updates a machine each night around 4:00 AM. It also reboots the machine as required.
I noticed Debian has checkrestart. The man page is at https://manpages.debian.org/bullseye/debian-goodies/checkrestart.8.en.html. I want to ensure I understand "Exit Status" correctly: Normally, the program will exit with error (1) if a non-root user tries to run it. Otherwise, it will always exit with error status 0. If the --terse switch is given, the exit code is 1 when there are deleted open files and 0 when there are none. This is intended for consumption by Nagios and similar automated monitoring tools. I think the script should use --terse, as in: if command -v checkrestart >/dev/null 2>&1; then if ! checkrestart --terse >/dev/null 2>&1; then needs_reboot=1 fi fi I think using an option like --terse is unusual to get an exit code that can be used in a script. I want to ensure it is correct. My question is, is that usage correct? Thanks in advance.
