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 directory
       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 argu‐
       ments, 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 existing delta type = D.  For further
			   information, see If the -a keyletter is not	speci‐
			   fied,  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 spec‐
			   ified, 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 key‐
       word substitution is direct, or Multi-line (M), in which	 keyword  sub‐
       stitution is followed by a carriage return.

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

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:\n: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.
