Sort Active Processes in Unix

Solution 1:

I would do something like:

ps -A -o cmd,etime --sort etime

If by 'process time' you mean elapsed wall clock time of the process. Other time options are:

   j     cutime       cumulative user time
   J     cstime       cumulative system time
   k     utime        user time

If I understand you well, you can run top and press T.

You should be able to use ps Ok (O - order, k - user time), and apply selection and formatting options as needed.
