The watch command

A cool little Linux command that I found out about called “watch”. It runs a command repeatedly displaying its output and errors (the first screenfull). it will run the command every 2 seconds you can change this using the -n parameter to specify another interval.

Again with thanks to the man pages and good old google.

To see what happens try this: watch -n 0 procinfo
