in reply to Whats a good process for archiving cron processed files?

Maybe PerlIO::gzip is what you're looking for. In the example below, the script adds compressed copies of itself to a single file.

# Invoke this script with a numerical argument n, and it
# will append n compressed copies of itself to the file
# foobar.gz.

use strict;
use warnings;

use PerlIO::gzip;

open my $fh, '>>:gzip', 'foobar.gz' or
  die "Failed to append to foobar.gz: $!";

for ( 1..( $ARGV[ 0 ] || 1 ) ) {
  local @ARGV = $0;
  print $fh ( <> );
}

close $fh;
