       sccs-delta, delta - make a delta to an SCCS file

       /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...

       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 contin-
       ues 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).

       The SID of the delta is not echoed to stdout.

       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  written  to  standard

       -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-sepa-
				   rated list. If -m is not used and the standard input is a ter-
				   minal, 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 sup-

       -y[comment]		   Supply  a  comment  for  the delta table (version log). A null
				   comment is accepted, and produces an empty commentary  in  the
				   log. If -y is not specified and the standard input is a termi-
				   nal, delta prompts with `comments?'. An unescaped NEWLINE ter-
				   minates the comment.

       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.

       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 specified, and the s.filename argument  was
	    not specified.

       Use the SCCS help command for explanations (see sccs-help(1)).

       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.
