Script to check for process & restart program if not found [duplicate]

Answer 1

if pidof -s CCCam > /dev/null; then
    echo 'It is already running!'
else
    echo 'process not found...'
fi

Answer 2

You can also use pgrep in this case. It looks for the process name CCCam in proc table.

if [[ $(pgrep CCCam) ]]; then
   echo "CCCam is running";
else
   echo "Not Running, so I must do something";
   # DO something ....
fi
