DESCRIPTION

       GNU cpio copies files between archives and directories.  It supports the following archive
       formats: old binary cpio, old portable cpio, SVR4 cpio with and without checksum, HP cpio,
       and various tar formats.

       The operation mode is requested by one of the following options:

       -o, --create
              Copy-out.   Read  a  list  of  file names from the standard input and create on the
              standard output (unless overridden by the  --file  option)  an  archive  containing
              these files.

       -i, --extract
              Copy-in.   Read the archive from standard input (or from the file supplied with the
              --file option) and extract files from it, or (if the -t option is given)  list  its
              contents  to  the  standard  output.  If one or more patterns are supplied, read or
              list only files matching these patterns.  The -t option alone implies -i.

       -p, --pass-through
              Pass-through.  Read a list of file names from the standard input and copy  them  to
              the specified directory.

       -?, --help
              Give a short help summary and exit.

       --usage
              Print a short usage message and exit.

       --version
              Print program version and exit.

OPTIONS

   Operation modifiers valid in any mode
       --block-size=BLOCK-SIZE
              Set the I/O block size to BLOCK-SIZE * 512 bytes.

       -B     Set the I/O block size to 5120 bytes.

       -c     Use the old portable (ASCII) archive format.  This is the same as -H odc.

       -C, --io-size=NUMBER
              Set the I/O block size to the given NUMBER of bytes.

       -D, --directory=DIR
              Change to directory DIR.

       --force-local
              Archive file is local, even if its name contains colons.

       -H, --format=FORMAT
              Use  given  archive  FORMAT.   Valid  formats  are (the number in parentheses gives
              maximum size for individual archive member):

              bin    The obsolete binary format.  (2147483647 bytes)

              odc    The old (POSIX.1) portable format. (8589934591 bytes)

              newc   The new (SVR4) portable format, which supports file systems having more than
                     65536 i-nodes. (4294967295 bytes)

              crc    The new (SVR4) portable format with a checksum added.

              tar    The old tar format. (8589934591 bytes)

              ustar  The POSIX.1 tar format.  Also recognizes GNU tar archives, which are similar
                     but not identical. (8589934591 bytes)

              hpbin  The obsolete binary format used by HPUX's cpio (which  stores  device  files
                     differently).

              hpodc  The  portable  format  used  by  HPUX's  cpio  (which  stores  device  files
                     differently).

       -R, --owner=[USER][:.][GROUP]
              In copy-in and copy-pass mode, set the  ownership  of  all  files  created  to  the
              specified   USER  and/or  GROUP.   In  copy-out  mode,  store  the  supplied  owner
              information in the archive.

              USER and GROUP are first looked up in the system user and group databases.  If  not
              found,  cpio  checks if they consist of decimal digits only and, if so, treats them
              as numeric UID and GID, correspondingly.

              To avoid the lookup and ensure that arguments are treated as numeric values, prefix
              them with a plus sign, e.g.: -R +0:+0.

       --quiet
              Do not print the number of blocks copied at the end of the run.

       --rsh-command=COMMAND
              Use remote COMMAND instead of rsh.

       -v, --verbose
              Verbosely list the files processed.

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

       -W, --warning=FLAG
              Controls–ł  warning  display.  The FLAG is one of none, to disable all warnings, all
              to  enable  them,  truncate,  to  enable  warnings  about  field  truncation,   and
              no-truncate, to disable them.

              Multiple -W options accumulate.

   Operation modifiers valid in copy-in and copy-out modes
       -F, --file=[[USER@]HOST:]ARCHIVE-FILE
              Use  this  ARCHIVE-FILE  instead  of  standard  input (in copy-in mode) or standard
              output (in copy-out mode).  Optional USER and HOST specify the user and host  names
              in case of a remote archive.

       -M, --message=STRING
              Print STRING when the end of a volume of the backup media is reached.

   Operation modifiers valid only in copy-in mode
       -b, --swap
              Swap  both  halfwords  of  words and bytes of halfwords in the data.  Equivalent to
              -sS.

       -f, --nonmatching
              Only copy files that do not match any of the given patterns.

       -n, --numeric-uid-gid
              In the verbose table of contents listing, show numeric UID and GID.

       -r, --rename
              Interactively rename files.

       -s, --swap-bytes
              Swap the bytes of each halfword in the files.

       -S, --swap-halfwords
              Swap the halfwords of each word (4 bytes) in the files.

       --to-stdout
              Extract files to standard output.

       -E, --pattern-file=FILE
              Read additional patterns specifying filenames to extract or list from FILE.

       --only-verify-crc
              When reading a CRC format archive, only verify  the  CRC's  of  each  file  in  the
              archive, without actually extracting the files.

   Operation modifiers valid only in copy-out mode
       -A, --append
              Append to an existing archive.

       --device-independent, --reproducible
              Create    reproducible    archives.    This   is   equivalent   to   --ignore-devno
              --renumber-inodes.

       --ignore-devno
              Store 0 in the device number field of each archive member, instead  of  the  actual
              device number.

       -O [[USER@]HOST:]ARCHIVE-NAME
              Use  ARCHIVE-NAME  instead  of  standard output. Optional USER and HOST specify the
              user and host names in case of a remote archive.

              The output archive name can be specified wither using  this  option,  or  using  -F
              (--file), but not both.

       --renumber-inodes
              Renumber inodes when storing them in the archive.

   Operation modifiers valid only in copy-pass mode
       -l, --link
              Link files instead of copying them, when possible.

   Operation modifiers valid in copy-in and copy-out modes
       --absolute-filenames
              Do not strip file system prefix components from the file names.

       --no-absolute-filenames
              Create all files relative to the current directory.

   Operation modifiers valid in copy-out and copy-pass modes
       -0, --null
              Filenames in the list are delimited by null characters instead of newlines.

       -a, --reset-access-time
              Reset the access times of files after reading them.

       -I [[USER@]HOST:]ARCHIVE-NAME
              Use ARCHIVE-NAME instead of standard input. Optional USER and HOST specify the user
              and host names in case of a remote archive.

              The input archive name can be specified wither  using  this  option,  or  using  -F
              (--file), but not both.

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

   Operation modifiers valid in copy-in and copy-pass modes
       -d, --make-directories
              Create leading directories where needed.

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

       --no-preserve-owner
              Do not change the ownership of the files.

       --sparse
              Write files with large blocks of zeros as sparse files.

       -u, --unconditional
              Replace all files unconditionally.

RETURN VALUE

       GNU cpio exits with code  0  if  it  was  able  to  successfully  complete  the  requested
       operation.  On errors, it exits with code 2.
