cdc - Changes the comments in a Source Code Control System
(SCCS) delta
cdc -rSID [-m] [MRlist] [-y] [comment] file...
cdc -rSID -mMRlist -ycomment -
The cdc command changes the Modification Requests (MRs)
and comments for the SID specified by the -r option for
each named Source Code Control System (SCCS) file.
Supplies a list of MR numbers for cdc to add or delete in
the SID specified by the -r option. You can use this
option only if the file has the v header flag set (see the
admin command). A null MR list has no effect.
In MRlist, MRs are separated by spaces, tab characters,
or both. To delete an MR, precede the MR number
with an ! (exclamation point). If the MR you
want to delete is currently in the list of MRs, it
is changed into a comment line. The cdc command
places a list of all deleted MRs in the comment
section of the delta and precedes them with a comment
line, indicating that the following MRs were
deleted.
If you do not specify the -m option, and the v
header flag is set, MRs are read from standard
input. If standard input is a terminal, the cdc
command prompts you for the MRs. The first newline
character not preceded by a \ (backslash) ends the
list on the command line. The cdc command continues
to take input until it reads an End-of-File
character or a blank line. MRs are always read
before comments (see the -y option). If the v flag
has a value, cdc interprets the value as the name
of a program that validates the MR numbers. If the
MR number validation program returns a nonzero exit
value, the cdc command stops and does not change
the MRs. Specifies the SCCS identification number
of the delta for which cdc will change the comments
or MRs. Specifies text to replace any comment
already existing for the delta specified by the -r
option. The cdc command keeps the existing comments
and precedes them by a comment line, stating
that they were changed. A null comment has no
effect.
If you do not specify -y, the cdc command reads
comments from standard input until it reads an Endof-File
character. If the standard input is a terminal,
the cdc command prompts for the comments and
also allows a blank line to end input. If the last
character of a line is a \ (backslash), the cdc
command ignores it and continues to read standard
input.
If cdc reads standard input for file names (that is, when
you specify a file name of - (dash)), you must use the -y
and -m options.
If you specify a directory name, cdc performs the
requested actions on all SCCS files in that directory
(that is, all files with names that have the s. prefix).
If you specify a - (dash) in place of file, cdc reads
standard input and interprets each line as the name of an
SCCS file. For more information on SCCS, see the Programming
Support Tools.
You can change the comments and MRs for an SID only if you
made the SID or you own the file and the directory. For
more information on the permissions needed to change SCCS
files, see the get command.
For information about exit values, see the OPTIONS section.
To change the comment for SID 1.3 of SCCS file s.test.c to
new comment, enter: cdc -r1.3 -y"new comment" s.test.c
