Linux Script to check if process is running and act on the result

Question

I have a process that fails regularly & sometimes starts duplicate instances..

When I run: ps x |grep -v grep |grep -c \"processname\" I will get: <

Answer 1

I cannot get case to work at all. Heres what I have:

#! /bin/bash

logfile="/home/name/public_html/cgi-bin/check.log"

case "$(pidof -x script.pl | wc -w)" in

0)  echo "script not running, Restarting script:     $(date)" >> $logfile
#  ./restart-script.sh
;;
1)  echo "script Running:     $(date)" >> $logfile
;;
*)  echo "Removed duplicate instances of script: $(date)" >> $logfile
 #   kill $(pidof -x ./script.pl | awk '{ $1=""; print $0}')
;;
esac

rem the case action commands for now just to test the script. the above pidof -x command is returning '1', the case statement is returning the results for '0'.

Anyone have any idea where I'm going wrong?

Solved it by adding the following to my BIN/BASH Script: PATH=$PATH:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
