Using bash scripts for process performance monitoring

Monitor a Linux process with a bash script implementation.

Monitor the process using the PS command, and use the Loop plus sleep time for continuous monitoring.

Usage:

PSMONITOR.SH-P [PID]-D [Interval]-n [Statistics count]

Parameters:

-p Monitored process ID

-D read performance data interval

-N statistics, up to the number of times, automatic exit
