NAME

       sccs-cdc, cdc - change the delta commentary of an SCCS delta

SYNOPSIS

       /usr/ccs/bin/cdc -rsid [-mmr-list] [ -y [comment]] s.filename...

DESCRIPTION

       cdc annotates the delta commentary for the SCCS delta ID (SID) specified by the -r option in each named s.file.

       If the v flag is set in the s.file, you can also use cdc to update the Modification Request (MR) list.

       If you checked in the delta, or, if you own the file and directory and have write permission, you can use cdc to annotate the commentary.

       Rather than replacing the existing commentary, cdc inserts the new comment you supply, followed by a line of the form:

	      *** CHANGED *** yy/mm/dd hh/mm/ss username

       above the existing commentary.

       If a directory is named as the s.filename argument, the cdc command applies to all s.files in that directory. Unreadable s.files produce an
       error; processing continues with the next file (if any). If `-' is given as the s.filename argument, each line of  the  standard  input	is
       taken as the name of an SCCS history file to be processed, and the -m and -y options must be used.

OPTIONS

       -rsid	       Specify the SID of the delta to change.

       -mmr-list       Specify	one  or  more MR numbers to add or delete. When specifying more than one MR on the command line, mr-list takes the
		       form of a quoted, space-separated list. To delete an MR number, precede it with a ! character (an  empty  MR  list  has	no
		       effect).  A  list of deleted MRs is placed in the comment section of the delta commentary.  If -m is not used and the stan-
		       dard input is a terminal, cdc prompts with MRs? for the list (before issuing the comments? prompt). -m is only useful  when
		       the  v flag is set in the s.file. If that flag has a value, it is taken to be the name of a program to validate the MR num-
		       bers.  If that validation program returns a  non-zero  exit  status,  cdc  terminates  and  the	delta  commentary  remains
		       unchanged.

       -y[comment]     Use  comment as the annotation in the delta commentary. The previous comments are retained; the comment is added along with
		       a notation that the commentary was changed. A  null comment leaves the commentary unaffected. If -y is  not  specified  and
		       the  standard input is a terminal, cdc prompts with comments?  for the text of the notation to be added.  An unescaped NEW-
		       LINE character terminates the annotation text.

EXAMPLES

       Example 1: Changing the annotated commentary

       The following command:

       example% cdc -r1.6 -y"corrected commentary" s.program.c

       produces the following annotated commentary for delta 1.6 in s.program.c:

       D 1.6 88/07/05 23:21:07 username 9 0 00001/00000/00000
       MRs:
       COMMENTS:
