Re: Is there a limit of files I can decompress and then open in a script, if I close each one before openning other?

Recommend PerlIO::gzip for reading gzipped files, e.g.

use strict;
use warnings;

use IO::File;
use PerlIO::gzip;

my $ifh = IO::File->new( $ifile, '<:gzip' )
    or die "Cannot open $ifile: $!\n";

while (<$ifh>) {
    ...
}
