UNIX for Dummies Questions & Answers

hi i am a newbie to linux , we use Communigate for our mail on Centos. my problem is how to stop exim from running at startup. If exim starts our users cannot send their mail. i have stopped it running on all run levels but if i check exim status it says : Exim is stopped but the pid is running. How can i write a shell script to check and stop exim and its pid from starting.

Replace exim executable with a shell script, hiding it in another dir or with a suffix?

pid is short for Process ID . This is the unique identity of the process in the run queue. I deduce that the status script is looking at a file which contains the PID of the "exim" process. Read the status script and find out where the file resides. If you are confident that the"exim" process is not running, delete the file.

thanks but how do i do that. dont be offended i have very little linux experience

Thanks but how do i do that, sorry to offend but i am very new to linux.

For instance, this short script starts qzzq and leaves a file with the pid, so you can ps -fp $pid to check on it, or kill -9 $pid to remove it, once you move the pid from the file to $pid.

Code:

#!/usr/bin/sh
 
nohup qzzq &
echo $! >/etc/qzzq.pid
