Is there a way to know the permissions for a given user (which is not the current user) for a specific file on Linux?
My question assume not switching user with su.

The requirement to avoid switching to the user's account is problematic; I don't think there is a good way to avoid that. – tripleee Dec 11 '22 at 16:21

This commands return 0, if youruser can read (-r), write (-w) or execute (-x) file or it returns 1 if youruser can't read, write or execute.
sudo -u youruser test -r /path/to/file
sudo -u youruser test -w /path/to/file
sudo -u youruser test -x /path/to/file

check this command: sudo -u youruser test -r /path/to/file | echo $? output of this command = exit code ( 0 or 1) – Garamoff Dec 11 '22 at 21:16
