SCCS-CDC(1) General Commands Manual SCCS-CDC(1)
sccs-cdc, cdc - change the delta commentary of an SCCS delta
/usr/sccs/cdc -rsid [ -mmr-list ] [ -y [ comment ] ] s.filename ...
cdc annotates the delta commentary for the SCCS delta ID (SID) speci-
fied 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 com-
ment 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.
-rsid Specify the SID of the delta to change.
Specify one or more MR numbers to add or delete. When specify-
ing more than one MR on the command line, mr-list takes the form
of a quoted, space-separated list. To delete an MR number, pre-
cede 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 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 vali-
dation 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 NEWLINE
character terminates the annotation text.
The following command:
example% cdc -r1.6 -y"corrected commentary" s.program.c
produces the following annotated commentary for delta 1.6 in s.pro-
