At times we may need to see the CPU load and CPU information .Usually in linux we can fulfill that with the help of /proc/cpuinfo .But we may require to know the CPU load at times on sampling time basis [ /500ms /sec /min....].So lets see how that can be achieved
Note
1. cat /proc/cpuinfo
will give processor Number
2. ps -AP lists the pid of process and processorId also[PSR-column]
will give processor Number
