tar Optionstar strips an initial `/' from
member names. This option disables that behavior. @FIXME-xref{}.
tar to preserve the access time field in a file's inode when
dumping it. @FIXME-xref{}.
tar will back them up
using simple or numbered backups, depending upon backup-type.
@FIXME-xref{}.
tar prints error messages for read errors
with the block number in the archive file. @FIXME-xref{}.
tar uses to blocking x 512 bytes per
record. @FIXME-xref{}.
tar to print periodic checkpoint messages as it
reads through the archive. Its intended for when you want a visual
indication that tar is still running, but don't want to see
`--verbose' output. @FIXME-xref{}.
tar will use the compress program when reading or writing the
archive. This allows you to directly act on archives while saving
space. @FIXME-xref{}.
tar archive, tar will archive the file that a symbolic
link points to, rather than archiving the symlink. @FIXME-xref{}.
tar will change its current directory
to dir before performing any operations. When this option is used
during archive creation, it is order sensitive. @FIXME-xref{}.
tar will skip files that match
pattern. @FIXME-xref{}.
tar will use the list of patterns
in the file file. @FIXME-xref{}.
tar will use the file archive as the tar archive it
performs operations on, rather than tar's compilation dependent
default. @FIXME-xref{}.
tar will use the contents of file as a list of archive members
or files to operate on, in addition to those specified on the
command-line. @FIXME-xref{}.
tar to interpret the filename given to `--file' as a local
file, even if it looks like a remote tape drive name. @FIXME-xref{}.
tar archive will have a group id of group,
rather than the group from the source file. group is first decoded
as a group symbolic name, but if this interpretation fails, it has to be
a decimal numeric group ID. @FIXME-xref{}.
Also see the comments for the --owner=user option.
tar to read or write archives through gzip,
allowing tar to directly operate on several kinds of compressed
archives transparently. @FIXME-xref{}.
tar will print out a short message summarizing the operations and
options to tar and exit. @FIXME-xref{}.
tar to exit successfully if it encounters an
unreadable file. See section Options to Help Read Archives.
tar Writes Files.)
tar will ignore zeroed blocks in the archive, which
normally signals EOF. See section Options to Help Read Archives.
tar that it is working with an old GNU-format
incremental backup archive. It is intended primarily for backwards
compatibility only. @FIXME-xref{}.
tar is performing multi-tape backups, script-file is run
at the end of each tape. @FIXME-xref{}.
tar should ask the user for confirmation before
performing potentially destructive options, such as overwriting files.
@FIXME-xref{}.
tar will not overwrite existing
files if this option is present. See section Changing How tar Writes Files.
tar to write name as a name
record in the archive. When extracting or listing archives, tar will
only operate on archives that have a label matching the pattern
specified in name. @FIXME-xref{}.
tar creates is a new GNU-format incremental backup, using
snapshot-file to determine which files to backup.
With other operations, informs tar that the archive is in incremental
format. @FIXME-xref{}.
tar will use permissions
for the archive members, rather than the permissions from the files.
The program chmod and this tar option share the same syntax
for what permissions might be. See section `File permissions' in GNU file utilities. This reference also
has useful information for those not being overly familiar with the Unix
permission system.
Of course, permissions might be plainly specified as an octal number.
However, by using generic symbolic modifications to mode bits, this allows
more flexibility. For example, the value `a+rw' adds read and write
permissions for everybody, while retaining executable bits on directories
or on any other file already marked as executable.
tar that it should create or otherwise operate on a
multi-volume tar archive. @FIXME-xref{}.
tar will only add files that have changed
since date. @FIXME-xref{}.
tar will only add files whose
contents have changed (as opposed to just `--newer', which will
also back up files for which any status information has changed).
tar will not recurse into directories unless a
directory is explicitly named as an argument to tar. @FIXME-xref{}.
tar is using the `--files-from' option, this option
instructs tar to expect filenames terminated with NUL, so
tar can correctly work with file names that contain newlines.
@FIXME-xref{}.
tar that it should use numeric user and group
IDs when creating a tar file, rather than names. @FIXME-xref{}.
tar from recursing into
directories that are on different file systems from the current
directory. @FIXME-xref{}.
tar should use user as the owner of members
when creating archives, instead of the user associated with the source
file. user is first decoded as a user symbolic name, but if
this interpretation fails, it has to be a decimal numeric user ID.
@FIXME-xref{}.
There is no value indicating a missing number, and `0' usually means
root. Some people like to force `0' as the value to offer in
their distributions for the owner of files, because the root user is
anonymous anyway, so that might as well be the owner of anonymous archives.
tar to create an archive that is compatible with Unix V7
tar. @FIXME-xref{}.
tar to create a POSIX compliant tar archive. @FIXME-xref{}.
tar is extracting an archive, it normally subtracts the users'
umask from the permissions specified in the archive and uses that
number as the permissions to create the destination file. Specifying
this option instructs tar that it should use the permissions directly
from the archive. See section Changing How tar Writes Files.
tar should reblock its input, for reading from pipes on
systems with buggy implementations. See section Options to Help Read Archives.
tar to use size bytes per record when accessing the
archive. @FIXME-xref{}.
tar Writes Files.
tar to remove the source file from the file system after
appending it to an archive. @FIXME-xref{}.
tar that is should use cmd to communicate with remote
devices. @FIXME-xref{}.
tar when running on machines with
small amounts of memory. It informs tar that the list of file
arguments has already been sorted to match the order of files in the
archive. See section Options to Help Read Archives.
tar will attempt to preserve the owner
specified in the tar archive with this option present. @FIXME-xref{}.
tar Writes Files.)
tar to mention directories its skipping over when operating
on a tar archive. @FIXME-xref{}.
tar will skip extracting
files in the archive until it finds one that matches name.
See section Coping with Scarce Resources.
tar uses when backing up files from the default
`~'. @FIXME-xref{}.
tar is writing as being
num x 1024 bytes long. @FIXME-xref{}.
tar will extract files to stdout rather than to the
file system. See section Changing How tar Writes Files.
tar Writes Files.
tar to remove the corresponding file from the file system
before extracting it from the archive. See section Changing How tar Writes Files.
tar to access the archive through prog, which is
presumed to be a compression program of some sort. @FIXME-xref{}.
tar should be more verbose about the operations its
performing. This option can be specified multiple times for some
operations to increase the amount of information displayed. @FIXME-xref{}.
tar will print an informational message about what version it is and a
copyright message, some credits, and then exit. @FIXME-xref{}.
tar will keep track
of which volume of a multi-volume archive its working in file.
@FIXME-xref{}.
