How do I sort PID by PID in Linux?

First, to sort by pid, in order from highest PID to lowest, we’d use this ps command: And to sort by pid, from low to high, again we remove the “-” from our argument: There are many, many more ways to sort ps command output, and you can find all of them in the Linux ps command man page.
