copied!<p>The <a href="http://search.cpan.org/perldoc/Archive::Tar" rel="nofollow noreferrer"><code>Archive::Tar</code></a> and <a href="http://perldoc.perl.org/File/Find.html" rel="nofollow noreferrer"><code>File::Find</code></a> modules will be helpful. A basic example is shown below. It just prints information about the files in a tar and the files in a directory tree.</p> <p>It was not clear from your question how you want to compare the files. If you need to compare the actual content, the <code>get_content()</code> method in <code>Archive::Tar::File</code> will likely be needed. If a simpler comparison is adequate (for example, name, size, and mtime), you won't need much more than methods used in the example below.</p> <pre><code>#!/usr/bin/perl use strict; use warnings; # A utility function to display our results. sub Print_file_info { print map("$_\n", @_), "\n"; } # Print some basic information about files in a tar. use Archive::Tar qw(); my $tar_file = 'some_tar_file.tar.gz'; my $tar = Archive::Tar->new($tar_file); for my $ft ( $tar->get_files ){ # The variable $ft is an Archive::Tar::File object. Print_file_info( $ft->name, $ft->is_file ? 'file' : 'other', $ft->size, $ft->mtime, ); } # Print some basic information about files in a directory tree. use File::Find; my $dir_name = 'some_directory'; my @files; find(sub {push @files, $File::Find::name}, $dir_name); Print_file_info( $_, -f $_ ? 'file' : 'other', -s, (stat)[9], ) for @files; </code></pre>
