Compress::Raw::Bzip2::FAQ -- Frequently Asked Questions about Compress::Raw::Bzip2

DESCRIPTION

Common questions answered.

Compatibility with Unix compress/uncompress.

This module is not compatible with Unix compress.

If you have the uncompress program available, you can use this to read compressed files

open F, "uncompress -c $filename |";
while (<F>)
{
    ...

Alternatively, if you have the gunzip program available, you can use this to read compressed files

open F, "gunzip -c $filename |";
while (<F>)
{
    ...

and this to write compress files, if you have the compress program available

open F, "| compress -c $filename ";
print F "data";
...
close F ;

Accessing .tar.Z files

See previous FAQ item.

If the Archive::Tar module is installed and either the uncompress or gunzip programs are available, you can use one of these workarounds to read .tar.Z files.

Firstly with uncompress

use strict;
use warnings;
use Archive::Tar;

open F, "uncompress -c $filename |";
my $tar = Archive::Tar->new(*F);
...

and this with gunzip

use strict;
use warnings;
use Archive::Tar;

open F, "gunzip -c $filename |";
my $tar = Archive::Tar->new(*F);
...

Similarly, if the compress program is available, you can use this to write a .tar.Z file

use strict;
use warnings;
use Archive::Tar;
use IO::File;

my $fh = new IO::File "| compress -c >$filename";
my $tar = Archive::Tar->new();
...
$tar->write($fh);
$fh->close ;
