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 argument, 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 argument is not specified.

       -n                              Retain the edited g-file, which is normally removed at the completion of processing.

       -p                              Display line-by-line differences (in diff(1) format) on the standard output.

       -s                              Silent.  Do not display warning or confirmation messages.  Do not suppress error messages (which are  writ-
                                       ten 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 validate the MR numbers. If that validation 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. A diagnostic results if the specified SID is ambiguous, 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 standard input is a terminal, delta prompts with `com-
                                       ments?'. An unescaped NEWLINE terminates the comment.

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.
