       delta - make a delta (change) to an SCCS file

       SID] list] mrlist] comment] files

       The  command  is used to permanently introduce into the named SCCS file
       changes that were made to the file retrieved by (called the g-file,  or
       generated file).	 See get(1).

       makes  a	 delta	to  each  named	 SCCS  file.  If a directory is named,
       behaves as though each file in the directory was specified as  a	 named
       file,  except that non-SCCS files (last component of the path name does
       not begin with and unreadable files are silently ignored.  If a name of
       is  given, the standard input is read (see WARNINGS).  Each line of the
       standard input is taken to be the name of an SCCS file to be processed.

       may issue prompts  on  the  standard  output,  depending	 upon  certain
       options	specified  and flags (see admin(1)) that may be present in the
       SCCS file (see the and options below).

       Option arguments apply independently to each named file.

	      Uniquely identifies which delta is to be made to the
			     SCCS file.	 Use of this option is necessary  only
			     if	 two  or  more	outstanding for editing on the
			     same SCCS file  were  done	 by  the  same	person
			     (login  name).   The SID value specified with the
			     option can be either the  SID  specified  on  the
			     command line or the SID to be made as reported by
			     the command (see get(1)).	A  diagnostic  results
			     if	 the specified SID is ambiguous, or, if neces‐
			     sary and omitted on the command line.

	      Suppresses issuing, on  the  standard  output,  of  the  created
			     SID  as  well  as	the  number of lines inserted,
			     deleted and unchanged in the SCCS file.

	      Specifies retention of the edited
			     g-file (normally removed at completion  of	 delta

	      Specifies a    list  (see	 get(1) for the definition of list) of
			     deltas which are to be when the file is  accessed
			     at the change level (SID) created by this delta.

	      If the	     SCCS file has the flag set (see admin(1)), a Mod‐
			     ification Request (MR) number be supplied as  the
			     reason for creating the new delta.

			     If is not used and the standard input is a termi‐
			     nal, the prompt is issued on the standard	output
			     before  the standard input is read.  If the stan‐
			     dard input	 is  not  a  terminal,	no  prompt  is
			     issued.   The  prompt  always precedes the prompt
			     (see the option).

			     MRs in a list are separated by blanks and/or  tab
			     characters.  An unescaped new-line character ter‐
			     minates the MR list.

			     Note that if the flag has a value (see admin(1)),
			     it	 is  assumed  to  be the name of a program (or
			     shell procedure) that is to validate the correct‐
			     ness  of the MR numbers.  If a non-zero exit sta‐
			     tus is returned  from  the	 MR  number-validation
			     program, assumes that the MR numbers were not all
			     valid and terminates.

	      Arbitrary text used to describe the reason for making the delta.
			     A null string is considered a valid comment.

			     If is not specified and the standard input	 is  a
			     terminal,	the  prompt  is issued on the standard
			     output before the standard input is read.	If the
			     standard  input  is  not a terminal, no prompt is
			     issued.  An unescaped new-line  character	termi‐
			     nates the comment text.

	      Causes	     to	 print	(on  the  standard output in a diff(1)
			     format) the  SCCS	file  differences  before  and
			     after the delta is applied.

   Environment Variables
       determines  the	interpretation	of  text  as single- and/or multi-byte

       determines the language in which messages are displayed.

       If or is not specified in the  environment  or  is  set	to  the	 empty
       string, the value of is used as a default for each unspecified or empty
       variable.  If is not specified or is set to the empty string, a default
       of  "C"	(see  lang(5))	is used instead of If any internationalization
       variable contains an invalid setting, behaves as if all	international‐
       ization variables are set to "C".  See environ(5).

   International Code Set Support
       Single- and multi-byte character code sets are supported.

       Use sccshelp(1) for explanations.

       SCCS  files can be any length, but the number of lines in the text file
       itself cannot exceed 99999 lines.

       Lines beginning with an ASCII  SOH  character  (octal  001)  cannot  be
       placed  in the SCCS file unless the SOH is escaped.  This character has
       special meaning to SCCS (see sccsfile(4)) and will cause an error.

       A of many SCCS files, followed by a of those files, should  be  avoided
       when the generates a large amount of data.  Instead, multiple sequences
       should be used.

       If the standard input is specified on the command line, the (if	neces‐
       sary)  and  options  must  also	be present.  Omission of these options
       causes an error.

       Comments can be of multiple lines.  The maximum length of  the  comment
       (total  length of all comment lines) cannot exceed 1024 bytes.  No line
       in a comment should have a length of more than 1000 bytes.

       All of the auxiliary files listed below, except	for  the  g-file,  are
       created	in  the same directory as the s-file (see get(1)).  The g-file
       is created in the user's working directory.

       g-file		      Existed before the execution  of	removed	 after
			      completion of (unless was specified).
       p-file		      Existed  before the execution of may exist after
			      completion of
       q-file		      Created during the execution  of	removed	 after
			      completion of
       x-file		      Created  during the execution of renamed to SCCS
			      file after completion of
       z-file		      Created during the execution of  removed	during
			      the execution of
       d-file		      Created  during  the  execution of removed after

			      and the g-file.
