Kill All Processes of A Particular User
Problem: I was having this problem that need to kill all processes of a user in a cron job and start the processes again using a in a particular user space.
Solution: Might not be the most elegant solution. However, I chose to go with pkill and su. So, a sample bash file:
#/bin/bash
/usr/bin/pkill -u userid
su - userid -c /path/to/startup
Then, just run the bash in a cron job.
