The current pidof completion supports only procps version. However
some Linux distributions like Ubuntu, Debian, use sysvinit-utils version
by default. And they have diffrent CLI flags. And there is another
pidof implementation on macOS. This patch supports those three versions.
Reference
- procps: https://man7.org/linux/man-pages/man1/pidof.1.html
- sysvinit-utils: https://manpages.debian.org/testing/sysvinit-utils/pidof.8.en.html
- nightmare-production: http://www.nightproductions.net/cli.htm
