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.


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


One of the following options must be used:
-A, --catenate, --concatenate
append tar files to an archive
-c, --create
create a new archive
-d, --diff, --compare
find differences between archive and file system
-r, --append
append files to the end of an archive
-t, --list
list the contents of an archive
-u, --update
only append files that are newer than the existing in archive
-x, --extract, --get
extract files from an archive
delete from the archive (not for use on mag tapes!)


-C, --directory DIR
change to directory DIR
-f, --file [HOSTNAME:]F
use archive file or device F (default "-", meaning stdin/stdout)
-j, --bzip2
filter archive through bzip2, use to decompress .bz2 files
-p, --preserve-permissions
extract all protection information
-v, --verbose
verbosely list files processed
-z, --gzip, --ungzip
filter the archive through gzip


don't change access times on dumped files
-b, --blocking-factor N
block size of Nx512 bytes (default N=20)
-B, --read-full-blocks
reblock as we read (for reading 4.2BSD pipes)
--backup BACKUP-TYPE
backup files instead of deleting them using BACKUP-TYPE simple or numbered
block the output of compression program for tapes
-C, --directory DIR
change to directory DIR
warn if number of hard links to the file on the filesystem mismatch the number of links recorded in the archive
print directory names while reading the archive
-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)
archive file is local even if has a colon
--format FORMAT
selects output archive format
v7 - Unix V7
oldgnu - GNU tar <=1.12
gnu - GNU tar 1.13
ustar - POSIX.1-1988
posix - POSIX.1-2001
-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
like this manpage, but not as cool
-i, --ignore-zeros
ignore blocks of zeros in archive (normally mean EOF)
ignore case when excluding files
don't exit with non-zero status on unreadable files
--index-file FILE
send verbose output to FILE instead of stdout
-j, --bzip2
filter archive through bzip2, use to decompress .bz2 files
-k, --keep-old-files
keep existing files; don't overwrite them from archive
-K, --starting-file F
begin at file F in the archive
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
change tapes after writing N*1024 bytes
-m, --touch, --modification-time
don't extract file modified time
-M, --multi-volume
create/list/extract multi-volume archive
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
match any subsequenceof the name's components with --exclude
use case-sensitive matching with --exclude
don't recurse into directories
apply user's umask when extracting files instead of recorded permissions
don't use wildcards with --exclude
wildcards do not match slashes (/) with --exclude
--files-from reads null-terminated names, disable --directory
always use numbers for user/group names
-o, --old-archive, --portability
like --format=v7; -o exhibits this behavior when creating an archive (deprecated behavior)
-o, --no-same-owner
do not attempt to restore ownership when extracting; -o exhibits this behavior when extracting an archive
-O, --to-stdout
extract files to standard output
--occurrence NUM
process only NUM occurrences of each named file; used with --delete, --diff, --extract, or --list
overwrite existing files and directory metadata when extracting
overwrite directory metadata when extracting
--owner USER
change owner of extraced files to USER
-p, --same-permissions, --preserve-permissions
extract all protection information
-P, --absolute-names
don't strip leading `/'s from file names
--pax-option KEYWORD-LIST
used only with POSIX.1-2001 archives to modify the way tar handles extended header keywords
like --format=posix
like --preserve-permissions --same-order
this option causes tar to store each file's ACLs in the archive.
this option causes tar to store each file's SELinux security context information in the archive.
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.
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.
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.

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.

The full documentation for tar is maintained as a Texinfo manual. If the info and tar programs are properly installed at your site, the command
info tar

should give you access to the complete manual.
