The --null option causes --files-from=file-of-names (-T file-of-names) to read file
names terminated by a NUL instead of a newline, so files whose
names contain newlines can be archived using --files-from.
--null
Only consider NUL terminated file names, instead of files that
terminate in a newline.
The --null option is just like the one in GNU
xargs and cpio, and is useful with the
-print0 predicate of GNU find. In
tar, --null also disables special handling for
file names that begin with dash.
This example shows how to use find to generate a list of files
larger than 800K in length and put that list into a file called
long-files. The -print0 option to find is just
like -print, except that it separates files with a NUL
rather than with a newline. You can then run tar with both the
--null and -T options to specify that tar get the
files from that file, long-files, to create the archive
big.tgz. The --null option to tar will cause
tar to recognize the NUL separator between files.
