NAME
tar - The GNU version of the tar archiving utility
SYNOPSIS
tar [ - ] A --catenate --concatenate | c --create | d --diff --compare
| --delete | r --append | t --list | u --update | x --extract --get
[ options ]
filename1 [ filename2, ... filenameN ]
directory1 [ directory2, ...directoryN ]
DESCRIPTION
This manual page documents the GNU version of tar , an archiving pro-
gram 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
archive.
EXAMPLES
tar -xvvf foo.tar
extract foo.tar
tar -xvvzf foo.tar.gz
extract gzipped foo.tar.gz
tar -cvvf foo.tar foo/
tar contents of folder foo in foo.tar
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
--anchored
force exclusion patterns to match initial subsequences
--atime-preserve
don't change access times on dumped files
-b, --blocking-factor N
use record size of Nx512 bytes (default N=20)
-B, --read-full-records
reblock as we read (for reading 4.2BSD pipes)
--backup [TYPE]
back up files instead of overwriting (TYPE=numbered, existing,
simple)
-C, --directory DIR
change to directory DIR
--checkpoint
print periodic checkpoints
--exclude=PATTERN
exclude files matching PATTERN
-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 -M)
--force-local
archive file is local even if it has a colon
-G, --incremental
create/list/extract old GNU-format incremental backup
-g, --listed-incremental F
create/list/extract new GNU-format incremental backup
--group G
set group to G while adding files
-h, --dereference
don't dump symlinks; dump the files they point to
--help print help message
-i, --ignore-zeros
ignore blocks of zeros in archive (normally mean EOF)
--ignore-case
ignore case when excluding files
--ignore-failed-read
don't exit with non-zero status on unreadable files
-j, --bzip2
filter archive through bzip2, use to decompress .bz2 files.
WARNING: some previous versions of tar used option -I to filter
through bzip2. When writing scripts, use --bzip2 instead of -j
so that both older and newer tar versions will work.
-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

change tapes after writing N*1024 bytes
-m, --touch
don't extract file modified time
-M, --multi-volume
create/list/extract multi-volume archive
--mode M
set permissions to M while adding files
-N, --after-date DATE, --newer DATE
only store files newer than DATE

only store files whose contents have changed after DATE
--no-anchored
allow exclusion patterns to match any substring (the default)
--no-ignore-case
match patterns case sensitively (the default)
--no-recursion
do not recurse into subdirectories
--no-same-owner
extract files with owner set to current user (the default for
non-root users)

-o, --old-archive, --portability
write a V7 format archive, rather than ANSI format
-O, --to-stdout

--posix
create POSIX compliant archive
--preserve
like -p -s
-R, --block-number
show block number within archive with each message
--record-size SIZE

--recursion
recurse into directories (the default)
--recursive-unlink
remove existing directories before extracting directories of the
same name
--remove-files
remove files after adding them to the archive
--rsh-command=CMD

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.

2cat ../<name>.tgz | ssh <user>@<remote_host> '(cd <path_to_where_it_shall_be_extracted>; tar xzvf -)'
(You can omit "f -", because through "f" you tell tar from where to extract which is by default stdout (so it needn't be specified).)
