#!/bin/bash
if ps -ef | grep -v grep | grep "process name" ; then
    echo "process running"
    exit 0

    echo "process not running"
    exit 0
fi

My main background for a recent years is MySQL DEV/DBA engineer but I’m also participating in wider range of tasks which could be likely called as DataOps/DevOps tasks. You can see my online CV here: http://catyellow.net
