Help

-v, --verbose
       List  the files processed, or with -t, give an `ls -l' style ta-
       ble of contents listing.  In a verbose table of  contents  of  a
       ustar  archive,  user and group names in the archive that do not
       exist on the local system are replaced by the names that  corre-
       spond  locally to the numeric UID and GID stored in the archive.

-V --dot
       Print a "." for each file processed.

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.

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.

In copy-pass mode, cpio copies files from one directory tree to another, combining the copy-out and copy-in steps without actually using an archive. It reads the list of files to copy from the stan- dard input; the directory into which it will copy them is given as a non-option argument.

OPTIONS

-0, --null
      In copy-out and copy-pass modes, read a list of filenames ter-
      minated  by  a  null  character  instead of a newline, so that
      files whose names contain newlines can be archived.  GNU  find
      is one way to produce a list of null-terminated filenames.

-a, --reset-access-time
      Reset the access times of files after reading them, so that it
      does not look like they have just been read.

-A, --append
      Append to an existing archive.  Only works in  copy-out  mode.
      The  archive  must  be a disk file specified with the -O or -F
      (--file) option.

-c    Identical to "-H newc", use the new  (SVR4)  portable  format.

-d, --make-directories
      Create leading directories where needed.

-E FILE, --pattern-file=FILE
      In copy-in mode, read additional patterns specifying filenames
      to  extract  or list from FILE.  The lines of FILE are treated
      as if they had been non-option arguments to cpio.

-i, --extract
      Run in copy-in mode.

-l, --link
      Link files instead of copying them, when possible.

-L, --dereference
      Dereference  symbolic links (copy the files that they point to
      instead of copying the links).

-m, --preserve-modification-time
      Retain previous file modification times when creating files.

--no-absolute-filenames
      In  copy-in  mode,  create  all  files relative to the current
      directory, even if they have an  absolute  file  name  in  the
      archive.

-o, --create
      Run in copy-out mode.

-p, --pass-through
      Run in copy-pass mode.

-v, --verbose
      List  the  files  processed, or with -t, give an `ls -l' style
      table of contents listing.

-V --dot
      Print a "." for each file processed.
