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 directories
       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

       --xattrs
              this option causes tar to store each file's extended  attributes
              in  the archive. This option also enables --acls and--selinux if
              they haven't been set already, due to the fact that the data for
              those are stored in special xattrs.

       --no-acls
              This  option  causes  tar  not  to store each file's ACLs in the
              archive and not to extract any ACL information in an archive.

              this option causes tar not to store each file's SELinux security
              context  information  in  the  archive  and  not  to extract any
              SELinux information in an archive.

       --no-xattrs
              this option  causes  tar  not  to  store  each  file's  extended
              attributes  in  the  archive  and  not  to  extract any extended
              attributes in an archive. This option also enables --no-acls and
              --no-selinux if they haven't been set already.

BUGS
       The GNU folks, in general, abhor man pages, and create  info  documents
       instead.   The  maintainer  of tar falls into this category.  Thus this
       man page may not be complete, nor current, and was included in the  Red
       Hat  CVS  tree because man is a great tool :).  This man page was first
       taken from Debian Linux and has since been loving updated here.

REPORTING BUGS
       Please report bugs via https://bugzilla.redhat.com
