PRS(1)                               BSD                                PRS(1)



NAME
     prs - print an SCCS file

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

DESCRIPTION
     prs prints, on the standard output, part or all of an SCCS (Source Code
     Control System) file in a user-supplied format.  If you name a directory,
     prs behaves as though each file in the directory is specified as a named
     file, except that it silently ignores non-SCCS and unreadable files.  If
     a dash (-) is given in place of a filename, prs reads the standard input,
     taking each line to be the name of an SCCS file or directory to be
     processed.  Options to prs may appear in any order.  Each argument
     applies independently to each named file.

OPTIONS
     -d[dataspec]Specify the output data specification.  The dataspec is a
                 string consisting of SCCS file data keywords interspersed
                 with optional user-supplied text.

     -r[SID]     Specify the SCCS Identification (SID) string of the delta for
                 which information is desired.  If you do not specify an SID,
                 then prs assumes the SID to be that of the most recently
                 created delta.

     -e          Request 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          Request 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]
                 Specify date-time as cutoff for requesting information.  This
                 cutoff date-time appears in the following form:

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

                 Units omitted from the date-time default to their maximum
                 possible values; that is, -c8502 is equivalent to
                 -c850228235959.  Any number of non-numeric characters may
                 separate the various two-digit pieces of the cutoff date in
                 the following form:
                 -c85/2/2 9:22:25.

     -a          Request printing of information for both removed (delta type
                 = R) and existing (delta type = D) deltas.  Refer to rmdel(1)
                 for more information.  If you do not specify the -a
                 keyletter, prs provides information only on existing deltas.

DATA KEYWORDS
     Data keywords specify those parts of an SCCS file to be retrieved and
     output.  All parts of an SCCS file have an associated data keyword.
     Refer to sccsfile(4) for more information about the structure of these
     file types.  There is no limit on the number of times a data keyword may
     appear in a dataspec.

     prs prints the user-supplied text, and 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
     "Multiline" (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 a carriage return/newline is specified by
     \n.  The default data keywords are:
     ":Dt:\t:DL:\nMRs:\n:MR:COMMENTS:\n:C:"
