In order to get Process Status (ps) of any process containing given string
(say 'mitesh'), we use to type following commands, which are long and
tedious to type.
$ ps auxww | grep "mitesh" | grep -v grep
Instead, if we type
$ psg.sh mitesh
which is more convenient to type. So what this 'psg.sh'
contains (I am assuming, that ~/bin is in $PATH):
$ vi ~/bin/psg.sh
function is ()
ps auxww | grep "$@" | grep -v "grep"
# END : psg.sh
