There is no way to ask for the n-th occurrence of a file.
Tape errors are handled ungracefully.
The u function key can be slow.
If the archive is a file on disk, flexible disk, or cartridge tape, and if the blocking factor specified on output
is not the default, the same blocking factor must be specified on input, because the blocking factor is not
explicitly stored in the archive. Updating or appending to the archive without following this rule can des-
troy it.
Some previous versions of tar have claimed to support the selective listing of file names using the t func-
tion key with a list. This appears to be an error in the documentation because the capability does not
appear in the original source code.
There is no way to restore an absolute path name to a relative position.
tar always pads information written to an archive up to the next multiple of the block size. Therefore, if
you are creating a small archive and write out one block of information, tar reports that one block was
written, but the actual size of the archive might be larger if the b function modifier is used.
Note that tar c0m is not the same as tar cm0
.
Do not create archives on block special devices. Attempting to do so can causes excessive wear, leading to
premature drive hardware failure.
DEPENDENCIES
