This script logs CPU load for a given process, every n seconds into a file
\nRequires <\/strong>: bash, ps, awk
\nExamples <\/strong>:
\npsmon <process name> [delay [logfile]]<\/em>
\npsmon sshd→<\/strong> logs %CPU load from process sshd, every 5 seconds, to file psmon.log.[day]
\npsmon q3ded 10 q3ded.log →<\/strong> logs %CPU load from process q3ded, every 10 seconds, to file q3ded.log
