"The cpio command has two unusual features. Unlike tar
, in which the files to back up are typed in as part of the
command, cpio reads the files to work with from the standard input
(in other words, the screen). This feature means that cpio must be
used as part of a multiple command or with a redirection pipe.
"cpio must always be used with one of three flags. Flags are
options that set the mode in which the command runs. Only one flag
can be used at a time, and it must come before any other options.
In addition, the choice of flags limits the options that can be
used. Each flag also has a gnu option that can used in its place.
The gnu option gives a convenient name for each flag: extract,
create, and pass- through."
