DESCRIPTION
This manual page documents the GNU version 1.13.25 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 func‐
tions. 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 ar‐
chive.
FUNCTION LETTERS
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
--delete
delete from the archive (not for use on mag tapes!)
-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 copy in archive
-x, --extract, --get
extract files from an archive
OTHER OPTIONS--atime-preserve
don't change access times on dumped files
-b, --block-size=N
block size of Nx512 bytes (default N=20)
-B, --read-full-blocks
reblock as we read (for reading 4.2BSD pipes)
-C, --directory=DIR
change to directory DIR
--checkpoint
print directory names while reading the archive
-f, --file=[HOSTNAME:]F
use archive file or device F (default /dev/rmt0)
--force-local
archive file is local even if has a colon
-F, --info-script=F, --new-volume-script=F
run script at end of each tape (implies -M)
-G, --incremental
create/list/extract old GNU-format incremental backup
-g, --listed-incremental=F
create/list/extract new GNU-format incremental backup
-h, --dereference
don't dump symlinks; dump the files they point to
-i, --ignore-zeros
ignore blocks of zeros in archive (normally mean EOF)
-j, --bzip2, --bunzip2
filter the archive through bzip2
--ignore-failed-read
don't exit with non-zero status on unreadable 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
-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, --modification-time
don't extract file modified time
-M, --multi-volume
create/list/extract multi-volume archive
-N, --after-date=DATE, --newer=DATE
only store files newer than DATE
-o, --old-archive, --portability
write a V7 format archive, rather than ANSI format
-O, --to-stdout
extract files to standard output
-p, --same-permissions, --preserve-permissions
extract all protection information
-P, --absolute-paths
don't strip leading `/'s from file names
--preserve
like -p -s
-R, --record-number
show record number within archive with each message
--recursive-unlink
Empty hierarchies prior to extracting directory
--remove-files
remove files after adding them to the archive
-s, --same-order, --preserve-order
list of names to extract is sorted to match archive
--same-owner
create extracted files with the same ownership
-S, --sparse
handle sparse files efficiently
-T, --files-from=F
get names to extract or create from file F
--null -T reads null-terminated names, disable -C
--totals
print total bytes written with --create
-v, --verbose
verbosely list files processed
-V, --label=NAME
create archive with volume name NAME
--version
print tar program version number
-w, --interactive, --confirmation
ask for confirmation for every action
-W, --verify
attempt to verify the archive after writing it
--exclude=FILE
exclude file FILE
-X, --exclude-from=FILE
exclude files listed in FILE
-Z, --compress, --uncompress
filter the archive through compress
-z, --gzip, --ungzip
filter the archive through gzip
--use-compress-program=PROG
filter the archive through PROG (which must accept -d)
--block-compress
block the output of compression program for tapes
-[0-7][lmh]
specify drive and density
BUGS
The GNU folks, in general, abhor man pages, and create info documents
instead. The maintainer of tar falls into this category. This man
page is neither complete, nor current, and was included in the Debian
Linux packaging of tar entirely to reduce the frequency with which the
lack of a man page gets reported as a bug in our defect tracking sys‐
tem.
If you really want to understand tar, then you should run info and read
the tar info pages, or use the info mode in emacs.
