in reply to Unusual IO::Uncompress::Gunzip behavior

You need to use the MultiStream option if you want to deal with concatenated gzip files.

use strict; use warnings; use IO::Compress::Gzip qw(gzip $GzipError) ; use IO::Uncompress::Gunzip qw(gunzip $GunzipError) ; my $gzipped; for my $txt ( qw(Alpha Beta Gamma)) { gzip \$txt => \$gzipped, Append => 1 or die "gzip failed: $GzipError\n"; } my $out; gunzip \$gzipped => \$out, MultiStream => 1 or die "gunzip failed: $GunzipError\n"; print "Uncompressed is:\n$out\n";

    Many thanks for pointing this out!

    Danged if I can figure out how I missed that after going through the docs so many times.

    Maybe it's time for reading glasses...

    Update: This test program will hang on *nix machines that have IO::Compress 2.015. I've found that you need at least 2.020, and have upgraded my systems to 2.055
