[rrc@Llawyr ~]$ cpio --help
Usage: cpio [OPTION...] [destination-directory]
GNU `cpio' copies files to and from archives

Examples:
# Copy files named in name-list to the archive
cpio -o < name-list [> archive]
# Extract files from the archive
cpio -i [< archive]
# Copy files named in name-list to destination-directory
cpio -p destination-directory < name-list

Main operation mode:
-i, --extract Extract files from an archive (run in copy-in
mode)
-o, --create Create the archive (run in copy-out mode)
-p, --pass-through Run in copy-pass mode
-t, --list Print a table of contents of the input

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
-C, --io-size=NUMBER Set the I/O block size to the given NUMBER of
bytes
--force-local Archive file is local, even if its name contains
colons
-f, --nonmatching Only copy files that do not match any of the given
patterns
-F, --file=[[USER@]HOST:]FILE-NAME
Use this FILE-NAME instead of standard input or
output. Optional USER and HOST specify the user
and host names in case of a remote archive
-H, --format=FORMAT Use given archive FORMAT
-M, --message=STRING Print STRING when the end of a volume of the
backup media is reached
-n, --numeric-uid-gid In the verbose table of contents listing, show
numeric UID and GID
--quiet Do not print the number of blocks copied
--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 Control warning display. Currently FLAG is one of
'none', 'truncate', 'all'. Multiple options
accumulate.

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
-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, don't actually
extract the files

Operation modifiers valid only in copy-out mode:

-A, --append Append to an existing archive.
-O [[USER@]HOST:]FILE-NAME Archive filename to use instead of standard
output. Optional USER and HOST specify the user
and host names in case of a remote 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 A list of filenames is terminated by a null
character instead of a newline
-a, --reset-access-time Reset the access times of files after reading them

-I [[USER@]HOST:]FILE-NAME Archive filename to use instead of standard input.
Optional USER and HOST specify the user and host
names in case of a remote archive
-L, --dereference Dereference symbolic links (copy the files
that they point to instead of copying the links).
-R, --owner=[USER][:.][GROUP] Set the ownership of all files created to the
specified USER and/or GROUP

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

-?, --help give this help list
--usage give a short usage message
--version print program version

Mandatory or optional arguments to long options are also mandatory or optional
for any corresponding short options.
