maybe - see what a command does before applying its changes

maybe was written by Philipp Emanuel Weidmann.

       This  manual page was written by Stephen Kitt <skitt@debian.org> for the Debian GNU/Linux system (but may
       be used by others).

maybe  runs the given command and intercepts any filesystems changes it attempts to make, indicating that
       they succeed without actually applying the changes. Once command has  finished,  maybe  reports  all  the
       changes attempted, and if there were any such changes, offers to re-run command without filtering them.

       maybe should never be used to check untrusted code since only a few system calls are blocked.
