How to check the status of a command launched in detached mode

I have a command (that would take a long time to run) launched in detached mode:

cmd1 &

After launching the command, I would like to get the status of this command (whether it has successfully executed or not). I know that if the command is not in detached mode (run without the &), I can check, after the command has finished, if $? equals to 0, but what if my command is detached? (moreover considering also that I do not have to know if the command has finished or not). Any ideas?

After launching, if you use `wait` command, see https://stackoverflow.com/questions/1570262/get-exit-code-of-a-background-process – Arnaud Valmary Apr 20 '23 at 15:53
`{ cmd; echo ret=$?; } >& /some/logfile &`? – pynexj Apr 20 '23 at 15:56
