sccs-cdc, cdc - change the delta commentary of an SCCS delta
/usr/ccs/bin/cdc -rsid [-mmr-list] [ -y [comment]]
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.
Specify the SID of the delta to change.
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 com-
mentary. If -m is not used and the standard 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 numbers. If that validation program
returns a non-zero exit status, cdc terminates and the
delta commentary remains unchanged.
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 unaf-
fected. 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.
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
