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 * 512bytes

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

-c                        Identical to "-H newc",use the new (SVR4) portable format.If you wish the old portable (ASCII) archive format, use "-H odc" instead.

-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:

--absolute-filenames   		do not strip leading file name components that
contain ".." and leading slashes from file names

-b, --swap                 Swap both halfwords of words and bytes of
halfwords in the data. Equivalent to -sS

-E, --pattern-file=FILE    In copy-in mode, read additional patterns specifying filenames to extract or list from FILE

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

--only-verify-crc      		When reading a CRC format archive in copy-in mode,only verify the CRC's of each file in the archive,don't actually extract the files

-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


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 for 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

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



Operation modifiers valid for 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

-u, --unconditional        Replace all files unconditionally
