9 /usr/ccs/bin/delta [-dnps] [-g sid-list | -gsid-list]
10 [-m mr-list | -mmr-list] [-r sid | -rsid]

12 /usr/xpg4/bin/delta [-dnps] [-g sid-list | -gsid-list]
15 [-m mr-list | -mmr-list] [-r sid | -rsid]
16 [-y [comment]] s.filename...

20 The delta utility checks in a record of the line-by-line differences
21 made to a checked-out version of a file under SCCS control. These
22 changes are taken from the writable working copy that was retrieved
23 using the SCCS get command (see sccs-get(1)). This working copy does
24 not have the `s.' prefix, and is also referred to as a g-file.
25 If a directory name is used in place of the s.filename argument, the
28 delta command applies to all s.files in that directory. Unreadable
29 s.files produce an error; processing continues with the next file (if
30 any). The use of `−' as the s.filename argument indicates that the
31 names of files are to be read from the standard input, one s.file per
32 line (requires -y, and in some cases, -m).
33 delta may issue prompts on the standard output depending upon the
36 options specified and the flags that are set in the s.file (see sccs-
37 admin(1), and the -m and -y options below, for details).
38 /usr/xpg4/bin/delta
40 The SID of the delta is not echoed to stdout.
41
43 The following options are supported:
44 -d Use command diff(1) instead of bdiff(1).
46 Returns exit status 2 if s.filename argu‐
47 ment is not specified.
48 -n Retain the edited g-file, which is normally
51 removed at the completion of processing.
52 -p Display line-by-line differences (in
55 diff(1) format) on the standard output.
56 -s Silent. Do not display warning or confir‐
59 mation messages. Do not suppress error
60 messages (which are written to standard
61 error).
62 -g sid-list | -gsid-list Specify a list of deltas to omit when the
65 file is accessed at the SCCS version ID
66 (SID) created by this delta. sid-list is a
67 comma-separated list of SIDs. To specify a
68 range of deltas, use a `−' separator
69 instead of a comma, between two SIDs in the
70 list.
71 -m mr-list | -mmr-list If the SCCS file has the v flag set (see
74 sccs-admin(1)), you must supply one or more
75 Modification Request (MR) numbers for the
76 new delta. When specifying more than one MR
77 number on the command line, mr-list takes
78 the form of a quoted, space-separated list.
79 If -m is not used and the standard input is
80 a terminal, delta prompts with MRs? for the
81 list (before issuing the comments? prompt).
82 If the v flag in the s.file has a value, it
83 is taken to be the name of a program to
84 validate the MR numbers. If that validation
85 program returns a non-zero exit status,
86 delta terminates without checking in the
87 changes.
88 -r sid | -rsid When two or more versions are checked out,
91 specify the version to check in. This SID
92 value can be either the SID specified on
93 the get command line, or the SID of the new
94 version to be checked in as reported by
95 get. A diagnostic results if the specified
96 SID is ambiguous, or if one is required but
97 not supplied.
98 -y[comment] Supply a comment for the delta table (ver‐
101 sion log). A null comment is accepted, and
102 produces an empty commentary in the log. If
103 -y is not specified and the standard input
104 is a terminal, delta prompts with `com‐
105 ments?'. An unescaped NEWLINE terminates
106 the comment.
107
110 See environ(5) for descriptions of the following environment variables
111 that affect the execution of delta: LANG, LC_ALL, LC_COLLATE, LC_CTYPE,
112 LC_MESSAGES, and NLSPATH.
113
115 The following exit values are returned:
116 0 Successful completion.
118 1 An error occurred and the -d option had not been specified.
121 2 An error occurred, the -d option had been specified, and the
124 s.filename argument was not specified.

175 Lines beginning with an ASCII SOH character (binary 001) cannot be
176 placed in the SCCS file unless the SOH is escaped. This character has
177 special meaning to SCCS (see sccsfile(4)) and produces an error.
