XENIX Programming Programming Commands
cdc (continued)
MRs in a list are separated by blanks and/or tab characters. An unescaped
newline character terminates the MR list.
Note that if the v flag has a value (see admin), it is taken to be the name of
a program or shell procedure that validates the correctness of the MR
numbers. If a nonzero exit status is returned from the MR number validation
program, cdc terminates, and the delta commentary remains unchanged.
-y[comment]
Arbitrary text used to replace the comment(s) already existing for the delta
specified by the -r option. The previous comments are kept and preceded by
a comment line stating that they were changed. A null comment has no
effect.
If -y is not specified and the standard input is a terminal, the prompt
comments? is issued on the standard output before the standard input is read;
if the standard input is not a terminal, no prompt is issued. An unescaped
newline character terminates the comment text.
In general, if you have made the delta, you can change its delta commentary; if you own
the file and directory, you can modify the delta commentary.
Examples
The following com mand
cdc - r1.6 - m"bl78-1 2345 !bl 77-54321 bl79-00001" - ytrouble
s.file
adds bl78-12345 and bl79-00001 to the MR list, removes bl77-54321 from the MR list,
and adds the com ment trouble to delta 1.6 of s.file. The following interactive sequence
has the same effect:
cdc -r1.6 s.fi le
MRs? !bl77-54321 b1 78-1 2345 bl79-00001
comments? trouble
Warning
If sees file names are supplied to the cdc command via the standard input (-on the
command line), then the -m and -y options must also be used.
