SYNOPSIS
SID [mrlist]] [comment]] files
DESCRIPTION
The command changes the for the SID specified by the option, of each named SCCS file.
is defined to be the Modification Request (MR) and comment information normally specified via the delta(1) command and options).
If a directory is named, behaves as if each file in the directory were specified as a named file, except that non-SCCS files (last compo-
nent of the path name does not begin with and unreadable files are silently ignored. If a name of is given, the standard input is read
(see each line of the standard input is taken to be the name of an SCCS file to be processed.
Options
Arguments to which can appear in any order, consist of option arguments and file names.
All of the described option arguments apply independently to each named file:
Used to specify the
SCCS IDentification (SID) string of a delta for which the delta commentary is to be changed.
If the SCCS file has the option set (see admin(1)), a list of MR numbers to be added and/or deleted in the delta commentary
of the SID specified by the 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(1). To delete an MR, precede the MR num-
ber with the character (see 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 is not used and the standard input is a terminal, the prompt is issued on the standard output before the standard
input is read; if the standard input is not a terminal, no prompt is issued. The prompt always precedes the prompt
(see option).
MRs in a list are separated by blanks and/or tab characters. An unescaped new-line character terminates the MRs
list.
Note that if the option has a value (see admin(1)), it is treated as the name of a program (or shell procedure) that
validates the correctness of the MR numbers. If a non-zero exit status is returned from the MR number validation
program, terminates and the delta commentary remains unchanged.
Arbitrary text used to replace the
comment or comments already existing for the delta specified by the option. Previous comments are kept and preceded
by a comment line stating that they were changed. A null comment has no effect.
If is not specified and the standard input is a terminal, the prompt is issued on the 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.
The exact permissions necessary to modify the SCCS file are documented in get(1). Simply stated, they are either:
o If you made the delta, you can change its delta commentary, or
o If you own the file and directory, you can modify the delta commentary.
