Hello, util-linux developers!
I use flock(1) from util-linux in my scripts, and with --wait or --nonblock
I would like to be able to distinguish between the "conflicting lock exists"
and "-c <command> exited with code 1" states.
Of course, I can always wrap the -c argument with something like
bash -c "<original_cmd_and_args> || exit 2" with yet another level of
quoting, but I think it is really ugly.
This problem can be solved for example by mapping the exit code 1
of the -c command to something else. I.e. to add something like
-m <number>
--map-exit-code-1-to <number>
where the exit code of flock(1) would be <number>, iff the -c <command> exits
with code 1.
The alternative would be to have user-settable exit code for
the "conflicting lock exists" failure.
What do you think about it? If you agree with the above syntax,
I can of course post a patch to flock(1).
Thanks,
-Yenya
