          This manual page documents the GNU version of ccccppppiiiioooo.  ccccppppiiiioooo
          copies files into or out of a cpio or tar archive, which is
          a file that contains other files plus information about
          them, such as their pathname, owner, timestamps, and access
          permissions.  The archive can be another file on the disk, a
          magnetic tape, or a pipe.  ccccppppiiiioooo has three operating modes.

          In copy-out mode, ccccppppiiiioooo 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.  A
          typical way to generate the list of filenames is with the
          ffffiiiinnnndddd command; you should give ffffiiiinnnndddd the -depth option to
          minimize problems with permissions on directories that are
          unwritable or not searchable.

          In copy-in mode, ccccppppiiiioooo 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



     Page 1                                           (printed 3/9/94)






     CCCCPPPPIIIIOOOO((((1111LLLL))))                  UUUUNNNNIIIIXXXX SSSSyyyysssstttteeeemmmm VVVV                  CCCCPPPPIIIIOOOO((((1111LLLL))))



          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, ccccppppiiiioooo 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 standard input; the directory into which it
          will copy them is given as a non-option argument.

          ccccppppiiiioooo supports the following archive formats: binary, old
          ASCII, new ASCII, crc, old tar, and POSIX.1 tar.  The binary
          format is obsolete because it encodes information about the
          files in a way that is not portable between different
          machine architectures.  The old ASCII format is portable
          between different machine architectures, but should not be
          used on file systems with more than 65536 i-nodes.  The new
          ASCII format is portable between different machine
          architectures and can be used on any size file system, but
          is not supported by all versions of ccccppppiiiioooo; currently, it is
          only supported by GNU and Unix System V R4.  The crc format
          is like the new ASCII format, but also contains a checksum
          for each file which ccccppppiiiioooo calculates when creating an archive
          and verifies when the file is extracted from the archive.

          The tar format is provided for compatability with the ttttaaaarrrr
          program.  It can not be used to archive files with names
          longer than 100 characters, and can not be used to archive
          "special" (block or character devices) files.  The POSIX.1
          tar format can not be used to archive files with names
          longer than 255 characters (less unless they have a "/" in
          just the right place).

          By default, ccccppppiiiioooo creates binary format archives, for
          compatibility with older ccccppppiiiioooo programs.  When extracting
          from archives, ccccppppiiiioooo automatically recognizes which kind of
          archive it is reading and can read archives created on
          machines with a different byte-order.

          Some of the options to ccccppppiiiioooo apply only to certain operating
          modes; see the SYNOPSIS section for a list of which options
          are allowed in which modes.

        OOOOPPPPTTTTIIIIOOOONNNNSSSS
          -_0, --_n_u_l_l
               In copy-out and copy-pass modes, read a list of
               filenames terminated by a null character instead of a
               newline, so that files whose names contain newlines can
               be archived.  GNU ffffiiiinnnndddd is one way to produce a list of
               null-terminated filenames.

          -_a, --_r_e_s_e_t-_a_c_c_e_s_s-_t_i_m_e
               Reset the access times of files after reading them, so
               that it does not look like they have just been read.

          -_A, --_a_p_p_e_n_d
               Append to an existing archive.  Only works in copy-out
               mode.  The archive must be a disk file specified with
               the -_O or -_F (--_f_i_l_e) option.

          -_b, --_s_w_a_p
               In copy-in mode, swap both halfwords of words and bytes
               of halfwords in the data.  Equivalent to -_s_S.  Use this
               option to convert 32-bit integers between big-endian
               and little-endian machines.

          -_B   Set the I/O block size to 5120 bytes.  Initially the
               block size is 512 bytes.

          --_b_l_o_c_k-_s_i_z_e=_B_L_O_C_K-_S_I_Z_E
               Set the I/O block size to BLOCK-SIZE * 512 bytes.

          -_c   Use the old portable (ASCII) archive format.

          -_C _I_O-_S_I_Z_E, --_i_o-_s_i_z_e=_I_O-_S_I_Z_E
               Set the I/O block size to IO-SIZE bytes.

          -_d, --_m_a_k_e-_d_i_r_e_c_t_o_r_i_e_s
               Create leading directories where needed.

          -_E _F_I_L_E, --_p_a_t_t_e_r_n-_f_i_l_e=_F_I_L_E
               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 ccccppppiiiioooo.

          -_f, --_n_o_n_m_a_t_c_h_i_n_g
               Only copy files that do not match any of the given
               patterns.

          -_F, --_f_i_l_e=_a_r_c_h_i_v_e
               Archive filename to use instead of standard input or
               output.  To use a tape drive on another machine as the
               archive, use a filename that starts with `HOSTNAME:'.
               The hostname can be preceded by a username and an `@'
               to access the remote tape drive as that user, if you
               have permission to do so (typically an entry in that
               user's `~/.rhosts' file).

          --_f_o_r_c_e-_l_o_c_a_l
               With -_F, -_I, or -_O, take the archive file name to be a
               local file even if it contains a colon, which would
               ordinarily indicate a remote host name.

               Use archive format FORMAT.  The valid formats are
               listed below; the same names are also recognized in
               all-caps.  The default in copy-in mode is to
               automatically detect the archive format, and in copy-
               out mode is "bin".

               bin  The obsolete binary format.

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

               tar  The old tar format.

               ustar
                    The POSIX.1 tar format.  Also recognizes GNU ttttaaaarrrr

               Link files instead of copying them, when possible.

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

               In copy-in mode and copy-pass mode, do not change the
               ownership of the files; leave them owned by the user
               extracting them.  This is the default for non-root
               users, so that users on System V don't inadvertantly
               give away files.

               In copy-out and copy-pass modes, set the ownership of
               all files created to the specified user and/or group.
               Either the user or the group, or both, must be present.
               If the group is omitted but the ":" or "." separator is
               given, use the given user's login group.  Only the

          support for `+' will be removed, because it is incompatible
          with the POSIX.2 standard.
