Copy-in mode
============
In copy-in mode, cpio copies files out of an archive or lists the
archive contents. It reads the archive from the standard input. Any
non-option command line arguments are shell globbing patterns; only
files in the archive whose names match one or more of those patterns are
copied from the archive. Unlike in the shell, an initial `.' in a
filename does match a wildcard at the start of a pattern, and a `/' in a
filename can match wildcards. If no patterns are given, all files are
extracted. Note:Options.
