Maybe this will help you on your way:
use strict;
use warnings;
# Save standard output handle
open(OLDOUT, ">&STDOUT");
# Reopen standard output as a pipe to the 'less' program
open(STDOUT, "| /usr/bin/less") or die "$!\n";
# Output some stuff
for (1..128) {
print "Line: $_\n";
}
# Close the modified STDOUT and reopen it as the original STDOUT again
close(STDOUT);
open(STDOUT, ">&OLDOUT") or die "Can't restore STDOUT: $!";
