I have a script that contains rm "$STDLOG" &>/dev/null
In the case of the file not existing, I want to proceed, which is why I’m tossing the results.
But I’m not accounting for the case of insufficient permissions, in which case the system asks a question and the script locks up.
Is there a general method for trapping on requests for input?
No. It is your job to instruct the command to either skip (e.g.
--interactive=never) or force (e.g.-f) the operation beforehand.
