Reading the name of a file in a .gz

[Yoda Pugsley]

Hello,

I need to read the name of a file inside a .gz. I know it should be the
zipped name - .gz, but the filenames are long and truncated sometimes. In
perl, what is the command to read the gzip -l into a variable? Something
like


my ($filename)

$filename == gzip -l ~/cdr/file.gz

will that work, or something like it?

Thanks,
JH

The following might work, provided your gzip program produces two lines
of output with the file name in the fourth field of the second line:

#!/usr/local/bin/perl
use strict;
use warnings;

my $f = 'file.gz';
$_ = (`gzip -l $f`)[1];
my $filename = (split)[3];
print "filename: $filename\n";
