/usr/bin/watch is a little utility that will erase the screen, run a command, sleep for a few seconds, then repeat. You can use it to follow files in /proc without continually re-typing the command.
This program has been around since 1991. How is it that I've been unaware of it all this time? How many other thousands of useful tools like this are lurking on my system right now that I've remained ignorant of?
So the advice of the day: spend some time getting to know your /usr/bin directory. Tomorrow, make it a point to learn a new emacs keybinding that you've never used before (if you don't know about M-/, start with that one).
