Tar on Windows XP
in [Perl]
|
From: David Walker on 29 Jan 2007 17:27 Hi I am trying to create a tar archive on Windows XP with the Perl code below. However, when I look at the archive created (using WinZip 10.0) all the directory information is lost, and when I untar it using WinZip all I get is all the files in the same directory. Can some kind person please tell me how I can create the tar file so that when it is untar'd the directory structure will be preserved. Thanks David use Archive::Tar; use IO::Zlib; use File::Find; $dir = "c:/docume~1/david/somedir"; $archive = "c:/docume~1/david/archive.tar"; $tar = Archive::Tar->new; (@files); find(\&wanted, $dir); $tar->add_files(@files); $tar->write($archive); sub wanted{ push(@files,$File::Find::name); }

By default, "Archive::Tar" is in a completely POSIX-compatible mode, which uses the POSIX-specification of "tar" to store files. For paths greather than 100 characters, this is done using the "POSIX header prefix". Non-POSIX-compatible clients may not support this part of the specification, and may only support the "GNU Extended Header" functionality. To facilitate those clients, you can set the $Archive::Tar::DO_NOT_USE_PREFIX variable to "true". See the "GLOBAL VARIABLES" section for details on this variable. -- end quote -- Hopefully, that deals with the problem you're facing. (If not, let us know - and also tell us which version of Archive::Tar you have.).) Cheers, Rob
From: David Walker on 30 Jan 2007 17:41 Rob Yes that worked! I was using Tar 1.07, which didn't have the DO_NOT_USE_PREFIX feature, so I've now installed Tar 1.30. Thanks for your help.
