I have this little bash function which I like to use to find out if a program is running, and to optionally kill it. Originally my goal was to keep it fitting inside a tweet, but adding helpful messaging just pushed it over. pgk () { [ -z "$*" ] && echo 'Usage: pgk <pattern>' && return 1; pgrep -fl $*; [ "$?" == "1" ] && echo 'No processes match' && return 1; echo 'Hit [Enter] to pkill, [Ctrl+C] to abort'; read && pkill -f $* }
