DESCRIPTION
This manual page documents the GNU version of tar, an archiving program designed to
store and extract files from an archive file known as a tarfile. A tarfile may be
made on a tape drive, however, it is also common to write a tarfile to a normal
file. The first argument to tar must be one of the options Acdrtux, followed by any
optional functions. The final arguments to tar are the names of the files or direc-
tories which should be archived. The use of a directory name always implies that
the subdirectories below should be included in the archive.
EXAMPLES
tar -xvf foo.tar
verbosely extract foo.tar
tar -xzf foo.tar.gz
extract gzipped foo.tar.gz
tar -cjf foo.tar.bz2 bar/
create bzipped tar archive of the directory bar called foo.tar.bz2
tar -xjf foo.tar.bz2 -C bar/
extract bzipped foo.tar.bz2 after changing directory to bar
tar -xzf foo.tar.gz blah.txt
extract the file blah.txt from foo.tar.gz
