A few observations.
First, the ping line in Jack's script surely should read:
system ("ping -c 1 $host");
so it sends only one ping packet instead of an unending stream of them.
Second, perl has "sleep" built in, so that line *can* read
sleep $sleep" ; }
(though the way Jack wrote it does work).
Third, if the program is run in the background (./alive &), won't the
"print" line block and stop the program from continuing to execute until it
is re-attached to a console?
