A \fItarfile\fR may be made on a tape drive, however, it is also common to write a \fItarfile\fR to a normal file. The first argument to \fBtar\fR must be one of the options \fBAcdrtux\fR, followed by any optional functions. The final arguments to \fBtar\fR 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. .SH EXAMPLES .TP .B tar -xvf foo.tar verbosely extract foo.tar .TP .B tar -xzf foo.tar.gz extract gzipped foo.tar.gz .TP .B tar -cjf foo.tar.bz2 bar/ create bzipped tar archive of the directory bar called foo.tar.bz2 .TP .B tar -xjf foo.tar.bz2 -C bar/ extract bzipped foo.tar.bz2 after changing directory to bar .TP .B tar -xzf foo.tar.gz blah.txt extract the file blah.txt from foo.tar.bz2 .SH "FUNCTION LETTERS" .TP .B One of the following options must be used: .TP .B -A, --catenate, --concatenate append tar files to an archive .TP .B -c, --create create a new archive .TP .B -d, --diff, --compare find differences between archive and file system .TP .B -r, --append append files to the end of an archive .TP .B -t, --list list the contents of an archive .TP .B -u, --update only append files that are newer than the existing in archive .TP .B -x, --extract, --get extract files from an archive .TP .B --delete delete from the archive (not for use on mag tapes!) .SH "COMMON OPTIONS" .TP .B -C, --directory DIR change to directory DIR .TP .B -f, --file [HOSTNAME:]F use archive file or device F (default "-", meaning stdin/stdout) .TP .B -j, --bzip2 filter archive through bzip2, use to decompress .bz2 files .TP .B -p, --preserve-permissions extract all protection information .TP .B -v, --verbose verbosely list files processed .TP .B -z, --gzip, --ungzip filter the archive through gzip .SH "ALL OPTIONS" .TP .B --atime-preserve don't change access times on dumped files .TP .B -b, --blocking-factor N block size of Nx512 bytes (default N=20) .TP .B -B, --read-full-blocks reblock as we read (for reading 4.2BSD pipes) .TP .B --backup BACKUP-TYPE backup files instead of deleting them using BACKUP-TYPE simple or numbered .TP .B --block-compress block the output of compression program for tapes .TP .B -C, --directory DIR change to directory DIR .TP .B --check-links warn if number of hard links to the file on the filesystem mismatch the number of links recorded in the archive .TP .B --checkpoint print directory names while reading the archive .TP .B -f, --file [HOSTNAME:]F use archive file or device F (default "-", meaning stdin/stdout) .TP .B -F, --info-script F --new-volume-script F run script at end of each tape (implies \fI--multi-volume\fR) .TP .B --force-local archive file is local even if has a colon .TP .B --format FORMAT selects output archive format .nf \fIv7\fR - Unix V7 \fIoldgnu\fR - GNU tar <=1.12 \fIgnu\fR - GNU tar 1.13 \fIustar\fR - POSIX.1-1988 \fIposix\fR - POSIX.1-2001 .fi .TP .B -g, --listed-incremental F create/list/extract new GNU-format incremental backup .TP .B -G, --incremental create/list/extract old GNU-format incremental backup .TP .B -h, --dereference don't dump symlinks; dump the files they point to .TP .B --help like this manpage, but not as cool .TP .B -i, --ignore-zeros ignore blocks of zeros in archive (normally mean EOF) .TP .B --ignore-case ignore case when excluding files .TP .B --ignore-failed-read don't exit with non-zero status on unreadable files .TP .B --index-file FILE send verbose output to FILE instead of stdout .TP .B -j, --bzip2 filter archive through bzip2, use to decompress .bz2 files .TP .B -k, --keep-old-files keep existing files; don't overwrite them from archive .TP .B -K, --starting-file F begin at file F in the archive .TP .B --keep-newer-files do not overwrite files which are newer than the archive .TP .B -l, --one-file-system stay in local file system when creating an archive .TP .B -L, --tape-length N change tapes after writing N*1024 bytes .TP .B -m, --touch, --modification-time don't extract file modified time .TP .B -M, --multi-volume create/list/extract multi-volume archive .TP .B --mode PERMISSIONS apply PERMISSIONS while adding files (see \fBchmod\fR(1)) .TP .B -N, --after-date DATE, --newer DATE only store files newer than DATE .TP .B --newer-mtime DATE like \fI--newer\fR, but with a DATE .TP .B --no-anchored match any subsequenceof the name's components with \fI--exclude\fR .TP .B --no-ignore-case use case-sensitive matching with \fI--exclude\fR .TP .B --no-recursion don't recurse into directories .TP .B --no-same-permissions apply user's umask when extracting files instead of recorded permissions .TP .B --no-wildcards don't use wildcards with \fI--exclude\fR .TP .B --no-wildcards-match-slash wildcards do not match slashes (/) with \fI--exclude\fR .TP .B --null \fI--files-from\fR reads null-terminated names, disable \fI--directory\fR .TP .B --numeric-owner always use numbers for user/group names .TP .B -o, --old-archive, --portability like \fI--format=v7\fR; \fI-o\fR exhibits this behavior when creating an archive (deprecated behavior) .TP .B -o, --no-same-owner do not attempt to restore ownership when extracting; \fI-o\fR exhibits this behavior when extracting an archive .TP .B -O, --to-stdout extract files to standard output .TP .B --occurrence NUM process only NUM occurrences of each named file;

The maintainer of \fBtar\fR falls into this category. Thus this man page may not be complete, nor current. .SH "SEE ALSO" The full documentation for .B tar is maintained as a Texinfo manual. If the .B info and .B tar programs are properly installed at your site, the command .IP .B info tar .PP should give you access to the complete manual. .SH "AUTHORS" .nf Debian Linux http://www.debian.org/ Mike Frysinger <vapier@gentoo.org> .fi
