No neeed to write a perl script for this kind of thing. Watch over
my shoulder for any length of time and you'll find me doing
something like this:
$ while :; do clear; date; echo; df -hi; sleep 2; done
Of course, the ``df -hi'' will change to whatever it is that I'm
interested in watching.
I've seen some Linux systems that have a facility called ``watch''
that does the same basic thing, but it seems rather a bit of
overkill to have a whole program devoted to a shell one-liner.
