How can I get my CPU utilization back to normal?

How to find the top processes in Linux?
The following command will show the list of top processes ordered by RAM and CPU use in descendant form (remove the pipeline and head if you want to see the full list): Brief explanation of above options used in above command. The -o (or –format) option of ps allows you to specify the output format.
What does it mean when your CPU usage is 100%?

How to check the CPU and memory usage of a process?
Brief explanation of above options used in above command. The -o (or –format) option of ps allows you to specify the output format. A favorite of mine is to show the processes’ PIDs ( pid ), PPIDs ( pid ), the name of the executable file associated with the process ( cmd ), and the RAM and CPU utilization ( %mem and %cpu, respectively).
