lockfile in pythonlockfile is one of my must haves, as it is a very useful semaphore lock file creator.
# lockfile --help Usage: lockfile -v | -nnn | -r nnn | -l nnn | -s nnn | -! | -ml | -mu | file ... # rpm -qf `which lockfile` procmail-3.22-25.1.el6.x86_64As can be seen above, /usr/bin/lockfile is part of procmail, which comes with its own dependencies (usually sendmail or postfix etc.). I did not like having to install those MTA type dependencies to setup procmail for locking purposes. This is the reason why I wrote lockfile.py.
