If a user wants to be able to directly use bzip2 files with tar, he can use the tar patch available from the LFS FTP site. This patch will add the -y option to tar which works the same as the -z option to tar (which can be used for gzip files).
Apply the patch by running the following command:
cd src &&
patch -i ../../gnutarpatch.txt &&
cd ..
Install Tar by running the following commands from the toplevel directory:
./configure --prefix=/usr --libexecdir=/usr/bin &&
make &&
make install &&
mv /usr/bin/tar /bin
The tar package contains the tar and rmt programs.
tar is an archiving program designed to store and extract files from an archive file known as a tar file.
rmt is a program used by the remote dump and restore programs in manipulating a magnetic tape drive through an interprocess communication connection.
