6 sccs-cdc, cdc - change the delta commentary of an SCCS delta
7
9 cdc -rsid [-mmr-list] [-y [comment]] s.filename...
10
13 cdc annotates the delta commentary for the SCCS delta ID (SID) speci‐
14 fied by the -r option in each named s.file.
15 If the v flag is set in the s.file, you can also use cdc to update the
18 Modification Request (MR) list.
19 If you checked in the delta, or, if you own the file and directory and
22 have write permission, you can use cdc to annotate the commentary.
23 Rather than replacing the existing commentary, cdc inserts the new com‐
26 ment you supply, followed by a line of the form:
27 *** CHANGED *** yy/mm/dd hh/mm/ss username
30 above the existing commentary.
33 If a directory is named as the s.filename argument, the cdc command
36 applies to all s.files in that directory. Unreadable s.files produce an
37 error; processing continues with the next file (if any). If `−' is
38 given as the s.filename argument, each line of the standard input is
39 taken as the name of an SCCS history file to be processed, and the -m
40 and -y options must be used.
41
43 -rsid Specify the SID of the delta to change.
44 -mmr-list Specify one or more MR numbers to add or delete. When
47 specifying more than one MR on the command line, mr-list
48 takes the form of a quoted, space-separated list. To
49 delete an MR number, precede it with a ! character (an
50 empty MR list has no effect). A list of deleted MRs is
51 placed in the comment section of the delta commentary.
52 If -m is not used and the standard input is a terminal,
53 cdc prompts with MRs? for the list (before issuing the
54 comments? prompt). -m is only useful when the v flag is
55 set in the s.file. If that flag has a value, it is taken
56 to be the name of a program to validate the MR numbers.
57 If that validation program returns a non-zero exit sta‐
58 tus, cdc terminates and the delta commentary remains
59 unchanged.
60 -y[comment] Use comment as the annotation in the delta commentary.
63 The previous comments are retained; the comment is added
64 along with a notation that the commentary was changed. A
65 null comment leaves the commentary unaffected. If -y is
66 not specified and the standard input is a terminal, cdc
67 prompts with comments? for the text of the notation to
68 be added. An unescaped NEWLINE character terminates the
69 annotation text.
