Hi , i have generated a shell script, i intend to display the cpu usage on my suse machine, however i need to show almost 100% cpu usage to be displayed when the script runs..... Any suggestion , can i install a particular application or invoke any process which would use all cpu..
Any idea..?

Code:

while true ; do set a=1 ; done &

Should do it.

Hello, welcome to LQ.

You can try to compile a big program with an aggressive -j flag, but don't complain if this results in burning you computer or even your house

No , i dont intend to implement it in my shell script, all i want it any name of a program or third party application that i can install and invoke its process, which would consume 100% cpu, will kill the process after my script is executed.. !

What syg00 suggested was to run the script he proposes in another shell, not to include it in yours.

Try Prime95, it will stress your CPU to its limit (also good for testing for heat problems and overall system stability)

Thank u all... For cpu usage. i installed apache.. ran httpd daemon, it did the needful..
Another small query... what if i wish to use my entire memory usage..? any script or program that i can envoke....??
