Name
       prs - display information from an SCCS file

Syntax
       prs [-d[dataspec]] [-r[SID]] [-e] [-l] [-a] files

Description
       The command prints on the standard output all or parts of an SCCS file in a user supplied format.  For further information, see If a direc-
       tory is named, behaves as though each file in the directory were specified as a named file, except that non-SCCS files (last  component	of
       the  path  name	does  not begin with s.), and unreadable files are silently ignored.  If a name of - is given, the standard input is read;
       each line of the standard input is taken to be the name of an SCCS file or directory to be processed; non-SCCS files and  unreadable  files
       are silently ignored.

       Arguments to which may appear in any order, consist of keyletter arguments, and file names.

Options
       All the described keyletter arguments apply independently to each named file:

       -a		   Displays printing of information for both removed and existing deltas.  For example, removed delta type = R, and exist-
			   ing delta type = D.	For further information, see If the -a keyletter is not specified, information	is  provided  only
			   for existing deltas.

       -d[dataspec]	   Displays  information  specified by dataspec.  The dataspec is a string consisting of SCCS file data keywords (see DATA
			   KEYWORDS) interspersed with optional user-supplied text.

       -e		   Displays information for all deltas created earlier than and including the delta designated by the -r keyletter.

       -l		   Displays information for all deltas created later than and including the delta designated by the -r keyletter.

       -r[SID]		   Indicates delta version number.  If no SID is specified, the SID of the most recently created delta is assumed.

Data Keywords
       Data keywords specify which parts of an SCCS file are to be retrieved and printed on the standard output.  All parts of an SCCS	file  have
       an associated data keyword.  For further information, see There is no limit on the number of times a data keyword may appear in a dataspec.

       The information printed by consists of the user supplied text and the appropriate values (extracted from the SCCS file) substituted for the
       recognized data keywords in the order of appearance in the dataspec.  The format of a data keyword value is either  Simple  (S),  in  which
       keyword substitution is direct, or Multi-line (M), in which keyword substitution is followed by a carriage return.

       User  supplied text is any text other than recognized data keywords.  A tab is specified by 	 and carriage return/new-line is specified by
       
.

Examples
       The following is an example of a command line and what it produces on the standard output:
       prs -d"Users and/or user IDs for :F: are:
:UN:" s.file

	      Users and/or user IDs for s.file are:
	      xyz
	      131
	      abc

       This is another example and its output.
       prs -d"Newest delta for pgm :M:: :I: Created :D: By :P:" -r s.file

	      Newest delta for pgm main.c: 3.7 Created 77/12/1 By case

       This is an example of a special case:
       prs s.file

       This is what it may produce on the standard output:

	      D 1.1 77/12/1 00:00:00 cas 1 000000/00000/00000 MRs: bl78-12345 bl79-54321 COMMENTS: this is the comment	line  for  s.file  initial
	      delta  for each delta table entry of the ``D'' type.  The only keyletter argument allowed to be used with the special case is the -a
	      keyletter.
