Process by CPU

Hello All,

I am preparing a script to capture the processes consuming more CPU.

So is there any way that i can sort & redirect to file only those processes consuming more than 5.0 % using ps command itself.

Regards

Ankit

You can use this command:

ps --no-headers -eo "%p %C %U %c %a" | sort -r -n -k 2 | awk '{if ($2 > 5.0) {print $0}}' > output-file

This command outputs the PID, CPU usage, user owning the process, process name and parameters to the output-file.

If you want to change the CPU usage maximum value, change it in the awk body ($2 > 5.0).

Try this

s --no-headers uax|sort -nrk6|head

The output contains below columns, RSS is the one you should target for memory utilization.

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
