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; processingcontinues 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 thes.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 argument is not specified.-n Retain the edited g-file, which
is normally removed at the com-
pletion of processing.SunOS 5.11 Last change: 1 Nov 1999 1

-p Display line-by-line differences
(in diff(1) format) on the stan-
dard output.-s Silent. Do not display warning
or confirmation messages. 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 bythis 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 Modifi-
cation Request (MR) numbers for the new delta. When specifying more than one MR number on thecommand 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 withMRs? for the list (before issu-
ing 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 validatethe MR numbers. If that valida-
tion program returns a non-zero
exit status, delta terminates without checking in the changes.-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. ASunOS 5.11 Last change: 1 Nov 1999 2

diagnostic results if the speci-
fied SID is ambiguous, or if one is required but not supplied.-y[comment] Supply a comment for the delta
table (version log). A null com-
ment is accepted, and produces an empty commentary in the log.If -y is not specified and the
standard input is a terminal, delta prompts with `comments?'. An unescaped NEWLINE terminates the comment. ENVIRONMENT VARIABLES See environ(5) for descriptions of the following environmentvariables 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 speci-
fied.2 An error occurred, the -d option had been specified,
and the s.filename argument was not specified. FILES d.file temporary file of differencesp.file lock file for a checked-out version
