Usage: tar [OPTION...] [FILE]...
GNU 'tar' saves many files together into a single tape or disk archive, and can
restore individual files from the archive.

  tar -cf archive.tar foo bar  # Create archive.tar from files foo and bar.
  tar -tvf archive.tar         # List all files in archive.tar verbosely.
  tar -xf archive.tar          # Extract all files from archive.tar.

 Local file name selection:
--add-file=FILE add given FILE to the archive (useful if its name starts with a dash)
-C, --directory=DIR change to directory DIR --exclude=PATTERN exclude files, given as a PATTERN --exclude-backups exclude backup and lock files --exclude-caches exclude contents of directories containing CACHEDIR.TAG, except for the tag file itself --exclude-caches-all exclude directories containing CACHEDIR.TAG --exclude-caches-under exclude everything under directories containing CACHEDIR.TAG --exclude-ignore=FILE read exclude patterns for each directory from FILE, if it exists --exclude-ignore-recursive=FILE read exclude patterns for each directory and its subdirectories from FILE, if it exists --exclude-tag=FILE exclude contents of directories containing FILE, except for FILE itself --exclude-tag-all=FILE exclude directories containing FILE --exclude-tag-under=FILE exclude everything under directories containing FILE --exclude-vcs exclude version control system directories --exclude-vcs-ignores read exclude patterns from the VCS ignore files --no-null disable the effect of the previous --null option --no-recursion avoid descending automatically in directories --no-unquote do not unquote input file or member names --no-verbatim-files-from -T treats file names starting with dash as options (default) --null -T reads null-terminated names; implies --verbatim-files-from --recursion recurse into directories (default)
-T, --files-from=FILE get names to extract or create from FILE --unquote unquote input file or member names (default) --verbatim-files-from -T reads file names verbatim (no option handling)
-X, --exclude-from=FILE exclude patterns listed in FILE
File name matching options (affect both exclude and include patterns):
--anchored patterns match file name start
--ignore-case ignore case
--no-anchored patterns match after any '/' (default for exclusion)
--no-ignore-case case sensitive matching (default)
--no-wildcards verbatim string matching
--no-wildcards-match-slash wildcards do not match '/'
--wildcards use wildcards (default for exclusion)
--wildcards-match-slash wildcards match '/' (default for exclusion)
Main operation mode:
-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 --delete delete from the archive (not on mag tapes!)

-n, --seek archive is seekable --no-check-device do not check device numbers when creating incremental archives --no-seek archive is not seekable --occurrence[=NUMBER] 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
--sparse-version=MAJOR[.MINOR] set version of the sparse format to use (implies --sparse)
-S, --sparse handle sparse files efficiently
Overwrite control:
-k, --keep-old-files don't replace existing files when extracting, treat them as errors --keep-directory-symlink preserve existing symlinks to directories when extracting --keep-newer-files don't replace existing files that are newer than their archive copies --no-overwrite-dir preserve metadata of existing directories --one-top-level[=DIR] create a subdirectory to avoid having loose files extracted --overwrite overwrite existing files when extracting --overwrite-dir overwrite metadata of existing directories when extracting (default) --recursive-unlink empty hierarchies prior to extracting directory --remove-files remove files after adding them to the archive --skip-old-files don't replace existing files when extracting, silently skip over them

Select output stream:
--ignore-command-error ignore exit codes of children --no-ignore-command-error treat non-zero exit codes of children as error
-O, --to-stdout extract files to standard output --to-command=COMMAND pipe extracted files to another program
Handling of file attributes:
--atime-preserve[=METHOD] preserve access times on dumped files, either by restoring the times after reading (METHOD='replace'; default) or by not setting the times in the first place (METHOD='system') --clamp-mtime only set time when the file is more recent than what was given with --mtime --delay-directory-restore delay setting modification times and permissions of extracted directories until the end of extraction --group=NAME force NAME as group for added files --group-map=FILE use FILE to map file owner GIDs and names --mode=CHANGES force (symbolic) mode CHANGES for added files --mtime=DATE-OR-FILE set mtime for added files from DATE-OR-FILE
-m, --touch don't extract file modified time --no-delay-directory-restore cancel the effect of --delay-directory-restore option --no-same-owner extract files as yourself (default for ordinary users) --no-same-permissions apply the user's umask when extracting permissions from the archive (default for ordinary users) --numeric-owner always use numbers for user/group names --owner=NAME force NAME as owner for added files --owner-map=FILE use FILE to map file owner UIDs and names
-p, --preserve-permissions, --same-permissions extract information about file permissions (default for superuser) --same-owner try extracting files with the same ownership as exists in the archive (default for superuser)
-s, --preserve-order, --same-order member arguments are listed in the same order as the files in the archive --sort=ORDER directory sorting order: none (default), name or inode

The backup suffix is '~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX. The version control may be set with --backup or VERSION_CONTROL, values are: none, off never make backups t, numbered make numbered backups nil, existing numbered if numbered backups exist, simple otherwise never, simple always make simple backups Valid arguments for the --quoting-style option are: literal shell shell-always c c-maybe escape locale clocale *This* tar defaults to: --format=gnu -f- -b20 --quoting-style=escape --rmt-command=/usr/lib/tar/rmt --rsh-command=/usr/bin/rsh
