cdc(CP)

Syntax

Description

Delta commentary is defined to be the Modification Request (MR) and comment information normally specified via the delta(CP) command's -m and -y options.

If a directory is named, cdc treats each file in the directory as if it had been specified as a named file, except that non-SCCS files and unreadable files are silently ignored. If a name of - is given, cdc reads standard input (see ``Warnings'' below) and each line of standard input is taken to be the name of an SCCS file to be processed.

All the described options apply independently to each named file:

-rSID

Used to specify the SCCS identification (SID) string of a delta for which the delta commentary is to be changed.

-mmrlist

If the SCCS file has the v flag set (see admin(CP)) then a list of MR numbers to be added and/or deleted in the delta commentary of the SID specified by the -r option may be supplied. A null MR list has no effect.

MR entries are added to the list of MRs in the same manner as that of delta(CP). In order to delete an MR, precede the MR number with the character ``!'' (see ``Examples'' below). If the MR to be deleted is currently in the list of MRs, it is removed and changed into a ``comment'' line. A list of all deleted MRs is placed in the comment section of the delta commentary and preceded by a comment line stating that they were deleted.

If -m is not used and the standard input is a terminal, the prompt ``MRs?'' is issued on standard output before standard input is read; if the standard input is not a terminal, no prompt is issued. The ``MRs?'' prompt always precedes the comments? prompt (see -y option).

MRs in a list are separated by blanks and/or tab characters. An unescaped new-line character terminates the MR list.

Note that if the v flag has a value (see admin(CP)), it is taken to be the name of a program (or shell procedure) which validates MR numbers. If a non-zero 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 standard input is a terminal, the prompt comments? is issued on standard output before standard input is read; if standard input is not a terminal, no prompt is issued. An unescaped new-line character terminates the comment text.

Simply stated, if you made the delta, or you own the file and directory, you can modify the delta commentary.

Examples

   cdc -r1.6 -m"bl78-12 !bl77-54 bl79-01" -ytrouble s.file

adds bl78-12 and bl79-01 to the MR list, removes bl77-54 from the MR list, and adds the comment trouble to delta 1.6 of s.file.

The same thing can be done as follows:

   cdc -r1.6 s.file
   MRs? !bl77-54 bl78-12 bl79-01
   comments? trouble
