Best regards, Oliver Reply Link venkat September 17, 2010, 4:56 pmHi, i have a query regarding CPU utilization and CPU percentage. top splits CPU usage between user, system processes and nice processes, we want the sum of the three. I like the "top|head -5" in particular - everything in one nutshell. Linux Proc Stat All rights reserved.
Try following examples, iostat -d -x
iostat -d -m -x
iostat -x -d 2All you have to do is pass -x option. For example: cpulimit -l 50 matho-primes 0 9999999999 > /dev/null & Note how the matho-primes process is now only using 50% of the available CPU time. Code: #!/bin/bash # # Process control # # This shell-script watch that
