cdc(1)


NAME

  cdc - Changes the comments in a Source Code Control System (SCCS) delta


SYNOPSIS

  cdc -rSID [-m] [MRlist] [-y] [comment] file...

  cdc -rSID -mMRlist -ycomment -

  The cdc command changes the Modification Requests (MRs) and comments for
  the SID specified by the -r option for each named Source Code Control
  System (SCCS) file.


OPTIONS

  -m[MRlist]
      Supplies a list of MR numbers for cdc to add or delete in the SID
      specified by the -r option.  You can use this option only if the file
      has the v header flag set (see the admin command).  A null MR list has
      no effect.

      In MRlist, MRs are separated by spaces, tab characters, or both. To
      delete an MR, precede the MR number with an ! (exclamation point). If
      the MR you want to delete is currently in the list of MRs, it is
      changed into a comment line.  The cdc command places a list of all
      deleted MRs in the comment section of the delta and precedes them with
      a comment line, indicating that the following MRs were deleted.

      If you do not specify the -m option, and the v header flag is set, MRs
      are read from standard input.  If standard input is a terminal, the cdc
      command prompts you for the MRs. The first newline character not
      preceded by a \ (backslash) ends the list on the command line.  The cdc
      command continues to take input until it reads an End-of-File character
      or a blank line.	MRs are always read before comments (see the -y
      option).	If the v flag has a value, cdc interprets the value as the
      name of a program that validates the MR numbers.	If the MR number
      validation program returns a nonzero exit value, the cdc command stops
      and does not change the MRs.

  -rSID
      Specifies the SCCS identification number of the delta for which cdc
      will change the comments or MRs.

  -y[comment]
      Specifies text to replace any comment already existing for the delta
      specified by the -r option.  The cdc command keeps the existing
      comments and precedes them by a comment line, stating that they were
      changed.	A null comment has no effect.

      If you do not specify -y, the cdc command reads comments from standard
      input until it reads an End-of-File character.  If the standard input
      is a terminal, the cdc command prompts for the comments and also allows
      a blank line to end input.  If the last character of a line is a \
      (backslash), the cdc command ignores it and continues to read standard
      input.

  If cdc reads standard input for file names (that is, when you specify a
  file name of - (dash)), you must use the -y and -m options.


DESCRIPTION

  If you specify a directory name, cdc performs the requested actions on all
  SCCS files in that directory (that is, all files with names that have the
  s. prefix).  If you specify a - (dash) in place of file, cdc reads standard
  input and interprets each line as the name of an SCCS file. For more
  information on SCCS, see the Programming Support Tools.

  You can change the comments and MRs for an SID only if you made the SID or
  you own the file and the directory.  For more information on the
  permissions needed to change SCCS files, see the get command.


EXIT STATUS

  For information about exit values, see the OPTIONS section.


EXAMPLES

  To change the comment for SID 1.3 of SCCS file s.test.c to new comment,
  enter:

       cdc -r1.3 -y"new comment" s.test.c
