NAME
delta - make a delta (change) to an SCCS file
SYNOPSIS
delta [-r SID][-s][-n][-g list ][-m mrlist ][-y comment ][-p] files
DESCRIPTION
The delta command is used to permanently introduce into the named SCCS file changes that were made
to the file retrieved by get (called the g-file, or generated file). See get(1).
delta makes a delta to each named SCCS file. If a directory is named, delta behaves as though each file
in the directory was specified as a named file, except that non-SCCS files (last component of the path name
does not begin with .s) and unreadable files are silently ignored. If a name of - is given, the standard
input is read (see WARNINGS). Each line of the standard input is taken to be the name of anSCCS file to be
processed.
delta may issue prompts on the standard output, depending upon certain options specified and flags (see
admin(1)) that may be present in the SCCS file (see the -m and -y options below).
Options
Option arguments apply independently to each named file.
-rSID Uniquely identifies which delta is to be made to the SCCS file. Use of this option is
necessary only if two or more outstanding
gets for editing (get -e) on the same
SCCS file were done by the same person (login name). The SID value specified with
the
-r option can be either the SID specified on the get command line or the
SID to
be made as reported by the
get command (see get(1)). A diagnostic results if the
specified SID is ambiguous, or, if necessary and omitted on the command line.
-s Suppresses issuing, on the standard output, of the created delta’s SID
as well as the
number of lines inserted, deleted and unchanged in the
SCCS file.
-n Specifies retention of the edited g-file (normally removed at completion of delta pro-
cessing).
-glist Specifies a list (see get(1) for the definition of list) of deltas which are to be ignored
when the file is accessed at the change level (
SID) created by this delta.
-m[mrlist] If the SCCS file has the v flag set (see admin(1)), a Modification Request (
MR) number
must be supplied as the reason for creating the new delta.
If
-m is not used and the standard input is a terminal, the prompt MRs? 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
MRs? prompt always precedes the comments?
prompt (see the -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(1)), it is assumed to be the name of a
program (or shell procedure) that is to validate the correctness of the MR numbers. If
a non-zero exit status is returned from the MR number-validation program,
delta
assumes that the MR numbers were not all valid and terminates.
-y[comment] Arbitrary text used to describe the reason for making the delta. A null string is con-
sidered a valid comment.
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 new-line character ter-
minates the comment text.
-p Causes delta to print (on the standard output in a diff(1) format) the SCCS file
differences before and after the delta is applied.
