cpio: Copy-out mode
3.1 Copy-out mode
=================
In copy-out mode, cpio copies files into an archive. It reads a list of
filenames, one per line, on the standard input, and writes the archive
onto the standard output. A typical way to generate the list of
filenames is with the find command; you should give 'find' the '-depth'
option to minimize problems with permissions on directories that are
unreadable.
Copy-out mode is requested by the '-o' ('--create') command line
option, e.g.:
% find | cpio -o > directory.cpio
The following options can be used in copy-out mode:
'-0'
'--null'
Filenames in the list are delimited by ASCII null characters
instead of newlines.

'-B'
