[sysvinit-devel] add quiet option for pidof

[Walter Harms]

Hi List,
i am a happy user of pidof and i am using it in scripts often
to check for a programm running like.

pidof programm >/dev/null || nohup programm &

i am always missing the -q what is common to other programm to
silence unwanted output. see below for a patch that add the -q
option. btw: pidof supports also -h but has no check and no usage.

hope that helps
