[UNIX] 유닉스/리눅스에서 tar로 압축하는 방법


1. 압축을 할때
tar cvzfp 압축할디렉토리명.tar.gz 압축할디렉토리명

2. 압축을 풀때
tar xvzfp 압축한디렉토리명.tar.gz



-c, --create create a new archive
-v, --verbose verbosely list files processed
-z, --gzip, --ungzip filter the archive through gzip
-f, --file=ARCHIVE use archive file or device ARCHIVE
-p, --same-permissions extract permissions information
--no-same-permissions do not extract permissions information
--preserve-permissions same as -p


---------------------------------------------------------------
GNU `tar' saves many files together into a single tape or disk archive, and
can restore individual files from the archive.

Usage: tar [OPTION]... [FILE]...

Examples:
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.

If a long option shows an argument as mandatory, then it is mandatory
for the equivalent short option also. Similarly for optional arguments.

Main operation mode:
-t, --list list the contents of an archive
-x, --extract, --get extract files from 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
-u, --update only append files newer than copy in archive
-A, --catenate append tar files to an archive
--concatenate same as -A
--delete delete from the archive (not on mag tapes!)

Operation modifiers:
-W, --verify attempt to verify the archive after writing it
--remove-files remove files after adding them to the archive
-k, --keep-old-files don't replace existing files when extracting
--overwrite overwrite existing files when extracting
-U, --unlink-first remove each file prior to extracting over it
--recursive-unlink empty hierarchies prior to extracting directory
-S, --sparse handle sparse files efficiently
-O, --to-stdout extract files to standard output
-G, --incremental handle old GNU-format incremental backup
-g, --listed-incremental=FILE
handle new GNU-format incremental backup
--ignore-failed-read do not exit with nonzero on unreadable files

Handling of file attributes:
--owner=NAME force NAME as owner for added files
--group=NAME force NAME as group for added files
--mode=CHANGES force (symbolic) mode CHANGES for added files
--atime-preserve don't change access times on dumped files
-m, --modification-time don't extract file modified time
--same-owner try extracting files with the same ownership
--no-same-owner extract files as yourself
--numeric-owner always use numbers for user/group names
-p, --same-permissions extract permissions information
--no-same-permissions do not extract permissions information
--preserve-permissions same as -p
-s, --same-order sort names to extract to match archive
--preserve-order same as -s
--preserve same as both -p and -s

Device selection and switching:
-f, --file=ARCHIVE use archive file or device ARCHIVE
--force-local archive file is local even if has a colon
--rsh-command=COMMAND use remote COMMAND instead of rsh
-[0-7][lmh] specify drive and density
-M, --multi-volume create/list/extract multi-volume archive
-L, --tape-length=NUM change tape after writing NUM x 1024 bytes
-F, --info-script=FILE run script at end of each tape (implies -M)
--new-volume-script=FILE same as -F FILE
--volno-file=FILE use/update the volume number in FILE

Device blocking:
-b, --blocking-factor=BLOCKS BLOCKS x 512 bytes per record
--record-size=SIZE SIZE bytes per record, multiple of 512
-i, --ignore-zeros ignore zeroed blocks in archive (means EOF)
-B, --read-full-records reblock as we read (for 4.2BSD pipes)

Archive format selection:
-V, --label=NAME create archive with volume name NAME
PATTERN at list/extract time, a globbing PATTERN
-o, --old-archive, --portability write a V7 format archive
--posix write a POSIX format archive
-j, --bzip2 filter the archive through bzip2
-z, --gzip, --ungzip filter the archive through gzip
-Z, --compress, --uncompress filter the archive through compress
--use-compress-program=PROG filter through PROG (must accept -d)

Local file selection:
-C, --directory=DIR change to directory DIR
-T, --files-from=NAME get names to extract or create from file NAME
--null -T reads null-terminated names, disable -C
--exclude=PATTERN exclude files, given as a globbing PATTERN
-X, --exclude-from=FILE exclude globbing patterns listed in FILE
-P, --absolute-names don't strip leading `/'s from file names
-h, --dereference dump instead the files symlinks point to
--no-recursion avoid descending automatically in directories
-l, --one-file-system stay in local file system when creating archive
-K, --starting-file=NAME begin at file NAME in the archive
-N, --newer=DATE only store files newer than DATE
--newer-mtime compare date and time when data changed only
--after-date=DATE same as -N
--backup[=CONTROL] backup before removal, choose version control
--suffix=SUFFIX backup before removal, override usual suffix

Informative output:
--help print this help, then exit
--version print tar program version number, then exit
-v, --verbose verbosely list files processed
--checkpoint print directory names while reading the archive
--totals print total bytes written while creating archive
-R, --block-number show block number within archive with each message
-w, --interactive ask for confirmation for every action
--confirmation same as -w

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:

t, numbered make numbered backups
nil, existing numbered if numbered backups exist, simple otherwise
never, simple always make simple backups

GNU tar cannot read nor produce `--posix' archives. If POSIXLY_CORRECT
is set in the environment, GNU extensions are disallowed with `--posix'.
Support for POSIX is only partially implemented, don't count on it yet.
ARCHIVE may be FILE, HOST:FILE or USER@HOST:FILE; and FILE may be a file
or a device. *This* `tar' defaults to `-f- -b20'.
