The same way as you would execute any other program on said
machine. It isn't Perl specific, but it's specific on the
remote (and local) machine configuration - and any routers/firewalls
in between.
Typical ways include using rsh (called remsh
on some OSses), or UUCP (who remembers working with UUCP?). Unsafe
methods, both of them. A someone safer method is the use of
ssh - but that's harder to script if you want
to make it secure.
But there are other ways. HTTP for instance, in combination with CGI.
Or the use of inetd. You could even share a disk with
a remote machine and trigger execution that way.
Note that none of the method is Perl specific, and none of the methods
is a "will work anywhere" solution.
