DESCRIPTION
The cdc command changes the Modification Requests (MRs) and comments for the
SID specified by the -r flag for each named Source Code Control System (SCCS)
file. If you specify a directory name, the cdc command 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 - (minus) in place of file, the cdc
command reads standard input and interprets each line as the name of an SCCS
file. For more information on SCCS comments and Modification Requests, see AIX
Operating System Programming Tools and Interfaces.
You can change the comments and MRs for an SID only if you made the SID or if
you own the file and the directory. For more information on the permissions
needed to change SCCS files, see "SCCS Files."
FLAGS
-m[mrlist] Supplies a list of MR numbers for the cdc command to add or
delete in the SID specified by the -r flag. You can only use
this flag if the file has the v header flag set (see Figure 2).
A null MR list has no effect.
In the mrlist, MRs are separated by blanks, 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 each MR with a comment line
indicating which MRs was deleted.

If you do not specify the -m flag 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
new-line 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 (Ctrl-D) or a blank line. MRs
are always read before comments (see the -y flag).
If the v flag has a value, the cdc command interprets the value
as the name of a program which validates the MR numbers. If the
MR number validation program returns a nonzero exit value, the
command stops and does not change the MRs.
-rSID Specifies the SCCS identification number of the delta for which
the cdc command can change the comments or MRs.
-y[comment] Specifies text to replace any comment already existing for the
delta specified by the -r flag. The cdc command keeps the
existing comments and precedes them with a comment line stating
that they were changed. A null comment has no effect.
If you do not specify the -y flag, the cdc command reads
comments from standard input until it reads an end-of-file
character. If the standard input is a work station, 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.
Note: If the cdc command reads standard input for file names
(that is, when you specify a file name of -), you must
use the -y and -m flags.
