This manual page documents the GNU version 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 functions. The final arguments to tar 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. |
One of the following options must be used: |
-A, --catenate, --concatenate |
append tar files to an archive |
|
create a new archive |
-d, --diff, --compare |
find differences between archive and file system |
|
delete from the archive (not for use on mag tapes!) |
|
append files to the end of an archive |
|
list the contents of an archive |
|
only append files that are newer than copy in archive |
|
extract files from an archive |
--atime-preserve |
don’t change access times on dumped files |
|
block size of Nx512 bytes (default N=20) |
|
reblock as we read (for reading 4.2BSD pipes) |
|
change to directory DIR |
|
print directory names while reading the archive |
|
use archive file or device F (default /dev/rmt0) |
|
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) |
|
create/list/extract old GNU-format incremental backup |
-g, --listed-incremental F |
create/list/extract new GNU-format incremental backup |
|
don’t dump symlinks; dump the files they point to |
|
ignore blocks of zeros in archive (normally mean EOF) |
-I, --bzip |
filter the archive through bzip2 |
|
don’t exit with non-zero status on unreadable files |
|
keep existing files; don’t overwrite them from archive |
|
begin at file F in the archive |
|
stay in local file system when creating an archive |
|
change tapes after writing N*1024 bytes |
|
don’t extract file modified time |
|
create/list/extract multi-volume archive |
|
only store files newer than DATE |
|
write a V7 format archive, rather than ANSI format |
|
extract files to standard output |
-p, --same-permissions, --preserve-permissions |
extract all protection information |
|
don’t strip leading ‘/’s from file names |
|
like -p -s |
|
show record number within archive with each message |
|
remove files after adding them to the archive |
|
list of names to extract is sorted to match archive |
|
create extracted files with the same ownership |
|
handle sparse files efficiently |
|
get names to extract or create from file F |
|
-T reads null-terminated names, disable -C |
|
print total bytes written with --create |
|
verbosely list files processed |
|
create archive with volume name NAME |
|
print tar program version number |
|
ask for confirmation for every action |
|
attempt to verify the archive after writing it |
|
exclude file FILE |
|
exclude files listed in FILE |
|
filter the archive through compress |
|
filter the archive through gzip |
--use-compress-program PROG |
filter the archive through PROG (which must accept -d) |
