      The field code for processor usage is "c". Possible values are: - not reported TS SCHED_OTHER FF SCHED_FIFO RR SCHED_RR ? But in this post we shall mostly focus on the unix style syntax. The reason is not that they’re not doing their job or wasting their time - it is mostly because they have automated a good deal of their routine tasks.

      This selects the processes whose effective group name or ID is in grouplist. See the -f option, which -F implies. -O format is like -o, but preloaded with some default columns.
