     CPIO         COHERENT (USENIX Association)        CPIO 
     NAME
          cpio - copy file archives in and out
     SYNOPSIS
          cpio -o[Bacv]
          cpio -i[Bcdfmrtuv] [pattern...]
          cpio -p[adlmruv] directory
     DESCRIPTION
          The cpio utility produces and reads files in the format
          specified by the cpio Archive/Interchange File Format
          specified in IEEE Std. 1003.1-1988.
          The cpio -i (copy in) utility extracts files from the
          standard input, which is assumed to be the product of a
          previous cpio -o . Only files with names that match patterns
          are selected.  Multiple patterns may be specified and if no
          patterns are specified, the default for patterns is
          selecting all files.  The extracted files are conditionally
          created and copied into the current directory, and possibly
          any levels below, based upon the options described below and
          the permissions of the files will be those of the previous
          cpio -o . The owner and group of the files will be that of
          the current user unless the user has appropriate privileges,
          which causes cpio to retains the owner and group of the
          files of the previous cpio -o .
          The cpio -p (pass) utility reads the standard input to
          obtain a list of path names of files that are conditionally
          created and copied into the destination directory based upon
          the options described below.
          If an error is detected, the cause is reported and the cpio
          utility will continue to copy other files.  cpio will skip
          over any unrecognized files which it encounters in the
          archive.
          The following restrictions apply to the cpio utility:
          1 Pathnames are restricted to 256 characters.
          2 Appropriate privileges are required to copy special files.
          3 Blocks are reported in 512-byte quantities.
        Options
          The following options are available:
          -B   Input/output is to be blocked 5120 bytes to the record.
               Can only be used with cpio -o or cpio -i for data that
               is directed to or from character special files.

          -a   Reset access times of input files after they have been
               copied.  When the -l option is also specified, the
               linked files do not have their access times reset.  Can
               only be used with cpio -o or cpio -i .
          -c   Write header information in ASCII character for 
	       portability.  Can only be used with cpio -i or cpio -o
               . Note that this option should always be used to write
               portable files.
          -d   Creates directories as needed.  Can only be used with
               cpio -i or cpio -p .
          -f   Copy in all files except those in patterns . Can only
               be used with cpio -i .
          -l   Whenever possible, link files rather than copying them.
               Can only be used with cpio -p .
          -m   Retain previous modification times.  This option is
               ineffective on directories that are being copied.  Can
               only be used with cpio -i or cpio -p .
          -r   Interactively rename files.  The user is asked whether
               to rename pattern each invocation.  Read and write
               permissions for /dev/tty are required for this option.
               If the user types a null line, the file is skipped.
               Should only be used with cpio -i or cpio -o .
          -t   Print a table of contents of the input.  No files are
               created.  Can only be used with cpio -i .
          -u   Copy files unconditionally; usually an older file will
               not replace a new file with the same name.  Can only be
               used with cpio -i or cpio -p .
          -v   Verbose: cause the names of the affected files to be
               printed.  Can only be used with cpio -i . Provides a
               detailed listing when used with the -t option.
        Operands
          The following operands are available:
          patterns  Simple regular expressions given in the name-
                    generating notation of the shell.
          directory The destination directory.
        Exit Status
          The cpio utility exits with one of the following values:
          0    All input files were copied.

          2    The utility encountered errors in copying or accessing
               files or directories.  An error will be reported for
               nonexistent files or directories, or permissions that
               do not allow the user to access the source or target
               files.
          The following command:

               ls | cpio -oc > ../newfile

          copies out the files listed by the ls utility and redirects
          them to the file ../newfile .
          The following command:

               cat newfile | cpio -id "memo/al" "memo/b*"

          uses the output file newfile from the cpio -o utility, takes
          those files that match the patterns memo/al and memo/b* ,
          creates the directories below the current directory, and
          places the files in the appropriate directories.
          The command

               find . -print | cpio -pdlmv newdir

          takes the file names piped to it from the find utility and
          copies or links those files to another directory named
          newdir, while retaining the modification time.
     FILES
          /dev/tty  used to prompt the user for information when the
                    -i or -r options are specified.
