NAME
     prs - print an SCCS file

SYNOPSIS
     prs [ -d[dataspec] ] [ -r[SID] ] [ -e ] [ -l ] [ -cdate-time
     ] [ -a ] file...

DESCRIPTION
     prs prints, on the standard output, parts or all of an SCCS
     file [see sccsfile(4)] in a user-supplied format.  If a
     directory is named, prs 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 prs, which may appear in any order, consist of
     keyletter arguments, and file names.

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

     -d[dataspec]        Used to specify the output data specifi-
                         cation.  The dataspec is a string con-
                         sisting of SCCS file data keywords (see
                         DATA KEYWORDS) interspersed with
                         optional user supplied text.

     -r[SID]             Used to specify the SCCS IDentification
                         (SID) string of a delta for which infor-
                         mation is desired.  If no SID is speci-
                         fied, the SID of the most recently
                         created delta is assumed.

     -e                  Requests information for all deltas
                         created earlier than and including the
                         delta designated via the -r keyletter or
                         the date given by the -c option.

     -l                  Requests information for all deltas
                         created later than and including the
                         delta designated via the -r keyletter or
                         the date given by the -c option.

                         c date-time The cutoff date-time -ccut-
                         off is in the form:

                              YY[MM[DD[HH[MM[SS]]]]]

     -cdate-time         Units omitted from the date-time default
                         to their maximum possible values; that
                         is, -c7502 is equivalent to
                         -c750228235959.  Any number of non-
                         numeric characters may separate the
                         various 2-digit pieces of the cutoff
                         date in the form:  "-c77/2/2 9:22:25".

     -a                  Requests printing of information for
                         both removed, i.e., delta type = R, [see
                         rmdel(1)] and existing, i.e., delta type
                         = D, deltas.  If the -a keyletter is not
                         specified, information for existing del-
                         tas only is provided.

DATA KEYWORDS
     Data keywords specify which parts of an SCCS file are to be
     retrieved and output.  All parts of an SCCS file [see
     sccsfile(4)] have an associated data keyword.  There is no
     limit on the number of times a data keyword may appear in a
     dataspec.

     The information printed by prs consists of:  (1) the user-
     supplied text; and (2) appropriate values (extracted from
     the SCCS file) substituted for  the  recognized data key-
     words in the order of appearance in the dataspec.  The for-
     mat 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 \t and carriage return/new-line is
     specified by \n.  The default data keywords are:

     As a special case:

          prs s.file

     may produce on the standard output:

          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.
