This is very minimal:
,----
| $SIG{INT} = sub { warn "ctl-c pressed!\n" };
|
| while (1) {
| print "hi\n";
| sleep 1;
| }
`----
If you run that it'll print "hi" forever, and a message when you press
ctl-c. You'll have to kill it to stop it (something to think about)
Try "perldoc -q trap signals" also, as well as the docs Paul pointed you at.
