I'm doing a piped open to less or more from perl on sensitive data like this: 
open (my $PAGER, "| $pager")
  or die "Can't fork a process for $pager: $!";
print $PAGER $text;
close $PAGER

[download]

Does anyone know if any temporary files are created by less or more (or perl) in this process? The file would never be more than maybe 50KB.

I realize that the data is plain text during viewing and I can live with that, however I would want to shred anything left on the filesystem, I'm just not sure if this ever exists on the filesystem.

The less man pages, website and Google haven't answered this for me.

Thanks,

Barry
