Common questions answered.
.Sh "Compatibility with Unix compress/uncompress."
.IX Subsection "Compatibility with Unix compress/uncompress."
This module is not compatible with Unix \f(CW\*(C`compress\*(C'\fR.
.PP
If you have the \f(CW\*(C`uncompress\*(C'\fR program available, you can use this to read
compressed files
.PP
.Vb 4
\&    open F, "uncompress -c $filename |";
\&    while (<F>)
\&    {
\&        ...
.Ve
.PP
Alternatively, if you have the \f(CW\*(C`gunzip\*(C'\fR program available, you can use
this to read compressed files
.PP
.Vb 4
\&    open F, "gunzip -c $filename |";
\&    while (<F>)
\&    {
\&        ...
.Ve
.PP
and this to write compress files, if you have the \f(CW\*(C`compress\*(C'\fR program
available
.PP
.Vb 4
\&    open F, "| compress -c $filename ";
\&    print F "data";
\&    ...
\&    close F ;
.Ve
.Sh "Accessing .tar.Z files"
.IX Subsection "Accessing .tar.Z files"
See previous \s-1FAQ\s0 item.
.PP
If the \f(CW\*(C`Archive::Tar\*(C'\fR module is installed and either the \f(CW\*(C`uncompress\*(C'\fR or
\&\f(CW\*(C`gunzip\*(C'\fR programs are available, you can use one of these workarounds to
read \f(CW\*(C`.tar.Z\*(C'\fR files.
.PP
Firstly with \f(CW\*(C`uncompress\*(C'\fR
.PP
.Vb 3
\&    use strict;
\&    use warnings;
\&    use Archive::Tar;
.Ve
.PP
.Vb 3
\&    open F, "uncompress -c $filename |";
\&    my $tar = Archive::Tar->new(*F);
\&    ...
.Ve
.PP
and this with \f(CW\*(C`gunzip\*(C'\fR
.PP
.Vb 3
\&    use strict;
\&    use warnings;
\&    use Archive::Tar;
.Ve
.PP
.Vb 3
\&    open F, "gunzip -c $filename |";
\&    my $tar = Archive::Tar->new(*F);
\&    ...
.Ve
.PP
Similarly, if the \f(CW\*(C`compress\*(C'\fR program is available, you can use this to
write a \f(CW\*(C`.tar.Z\*(C'\fR file
.PP
.Vb 4
\&    use strict;
\&    use warnings;
\&    use Archive::Tar;
\&    use IO::File;
.Ve
.PP
.Vb 5
\&    my $fh = new IO::File "| compress -c >$filename";
\&    my $tar = Archive::Tar->new();
\&    ...
\&    $tar->write($fh);
\&    $fh->close ;
