or numbered
--block-compress

match the number of links recorded in the archive
--checkpoint

-f, --file [HOSTNAME:]F
use archive file or device F (default "-", meaning stdin/stdout)
-F, --info-script F --new-volume-script F
run script at end of each tape (implies --multi-volume)
--force-local
archive file is local even if has a colon
--format FORMAT
selects output archive format

-g, --listed-incremental F
create/list/extract new GNU-format incremental backup
-G, --incremental
create/list/extract old GNU-format incremental backup
-h, --dereference
don't dump symlinks; dump the files they point to
--help like this manpage, but not as cool
-i, --ignore-zeros
-k, --keep-old-files
keep existing files; don't overwrite them from archive
-K, --starting-file F
begin at file F in the archive
--keep-newer-files
do not overwrite files which are newer than the archive
-l, --one-file-system
stay in local file system when creating an archive
-L, --tape-length N

don't extract file modified time
-M, --multi-volume
create/list/extract multi-volume archive
--mode PERMISSIONS
apply PERMISSIONS while adding files (see chmod(1))
-N, --after-date DATE, --newer DATE
only store files newer than DATE
--newer-mtime DATE
like --newer, but with a DATE
--no-anchored
match any subsequenceof the name's components with --exclude
--no-ignore-case
use case-sensitive matching with --exclude
--no-recursion
don't recurse into directories
--no-same-permissions
apply user's umask when extracting files instead of recorded
permissions
--no-wildcards
don't use wildcards with --exclude
--no-wildcards-match-slash
wildcards do not match slashes (/) with --exclude
--null --files-from reads null-terminated names, disable --directory
--numeric-owner
process only the NUMBERth occurrence of each file in the
archive; this option is valid only in conjunction with one of
the subcommands --delete, --diff, --extract or --list and when a
list of files is given either on the command line or via the -T
option; NUMBER defaults to 1
--overwrite
overwrite existing files and directory metadata when extracting
--overwrite-dir
overwrite directory metadata when extracting
--owner USER
change owner of extraced files to USER
-p, --same-permissions, --preserve-permissions
extract all protection information

--preserve
like --preserve-permissions --same-order
--acls this option causes tar to store each file's ACLs in the archive.
--selinux
this option causes tar to store each file's SELinux security
context information in the archive.
--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.
--no-selinux
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.
--recursive-unlink

--same-owner
create extracted files with the same ownership
--show-defaults
display the default options used by tar
--show-omitted-dirs
print directories tar skips while operating on an archive
--strip-components NUMBER, --strip-path NUMBER

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

The full documentation for tar is maintained as a Texinfo manual. If
the info and tar programs are properly installed at your site, the com-
mand
info tar
should give you access to the complete manual.
