User Commands sccs-delta(1)
NAME
sccs-delta, delta - make a delta to an SCCS file
SYNOPSIS
/usr/ccs/bin/delta [-dnps] [-g sid-list | -gsid-list] [-
m mr-list | -mmr-list] [-r sid | -rsid] [ -y [comment]]
s.filename...
/usr/xpg4/bin/delta [-dnps] [-g sid-list | -gsid-list] [-
m mr-list | -mmr-list] [-r sid | -rsid] [ -y [comment]]
s.filename...
DESCRIPTION
The delta utility checks in a record of the line-by-line
differences made to a checked-out version of a file under
SCCS control. These changes are taken from the writable
working copy that was retrieved using the SCCS get command
(see sccs-get(1)). This working copy does not have the `s.'
prefix, and is also referred to as a g-file.
If a directory name is used in place of the s.filename argu-
ment, the delta command applies to all s.files in that
directory. Unreadable s.files produce an error; processing
continues with the next file (if any). The use of `-' as the
s.filename argument indicates that the names of files are to
be read from the standard input, one s.file per line
(requires -y, and in some cases, -m).
delta may issue prompts on the standard output depending
upon the options specified and the flags that are set in the
s.file (see sccs-admin(1), and the -m and -y options below,
for details).
/usr/xpg4/bin/delta
The SID of the delta is not echoed to stdout.
OPTIONS
The following options are supported:
-d Use command diff(1) instead
of bdiff(1). Returns exit
status 2 if s.filename argu-
ment is not specified.
-n Retain the edited g-file,
which is normally removed at
the completion of process-
ing.

User Commands sccs-delta(1)
-p Display line-by-line differ-
ences (in diff(1) format) on
the standard output.
-s Silent. Do not display
warning or confirmation mes-
sages. Do not suppress
error messages (which are
written to standard error).
-g sid-list | -gsid-list Specify a list of deltas to
omit when the file is
accessed at the SCCS version
ID (SID) created by this
delta. sid-list is a comma-
separated list of SIDs. To
specify a range of deltas,
use a `-' separator instead
of a comma, between two SIDs
in the list.
-m mr-list | -mmr-list If the SCCS file has the v
flag set (see sccs-
admin(1)), you must supply
one or more Modification
Request (MR) numbers for the
new delta. When specifying
more than one MR number on
the command line, mr-list
takes the form of a quoted,
space-separated list. If -m
is not used and the standard
input is a terminal, delta
prompts with MRs? for the
list (before issuing the
comments? prompt). If the v
flag in the s.file has a
value, it is taken to be the
name of a program to vali-
date the MR numbers. If that
validation program returns a
non-zero exit status, delta
terminates without checking
in the changes.

User Commands sccs-delta(1)
-r sid | -rsid When two or more versions
are checked out, specify the
version to check in. This
SID value can be either the
SID specified on the get
command line, or the SID of
the new version to be
checked in as reported by
get. A diagnostic results if
the specified SID is ambigu-
ous, or if one is required
but not supplied.
-y[comment] Supply a comment for the
delta table (version log). A
null comment is accepted,
and produces an empty com-
mentary in the log. If -y is
not specified and the stan-
dard input is a terminal,
delta prompts with `com-
ments?'. An unescaped NEW-
LINE terminates the comment.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment
variables that affect the execution of delta: LANG, LC_ALL,
LC_COLLATE, LC_CTYPE, LC_MESSAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred and the -d option had not been
specified.
2 An error occurred, the -d option had been speci-
fied, and the s.filename argument was not speci-
fied.

DIAGNOSTICS
Use the SCCS help command for explanations (see sccs-
help(1)).
WARNINGS
Lines beginning with an ASCII SOH character (binary 001)
cannot be placed in the SCCS file unless the SOH is escaped.
This character has special meaning to SCCS (see sccsfile(4))
and produces an error.
