 Name

    prs - print an SCCS file

 Syntax

    prs [-d[dataspec]] [-r[SID]] [-e] [-l] [-c[date-time]] [-a] files
    prs -

 Description

    The prs command prints, on standard output, parts or all of an SCCS file
    (see sccsfile(FP)) 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 and unreadable files are silently
    ignored.  If a name of ``-'' is given, the standard input is read; each
    line of standard input is taken to be the name of an SCCS file or direc-
    tory to be processed; non-SCCS files and unreadable files are silently
    ignored.

    Arguments to prs may appear in any order.  All the described arguments
    apply independently to each named file:

    -d[dataspec] Used to specify the output data specification.  The dataspec
                 is a string consisting 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 information 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 option 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 option or the date
                 given by the -c option.

    -c[date-time]
                 The cutoff [date-time] is in the form:
                         YY[MM[DD[HH[MM[SS]]]]]
                 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 two-digit pieces of the cutoff date in
                 the form:  -c77/2/2 9:22:25.  The -c option must be used
                 with the -e or -l option.

    -a           Requests printing of information for both removed (delta
                 type R) and existing (delta type D) deltas (see rmdel(CP).
                 If -a is not specified, information is provided for existing
                 deltas only.

 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(FP)) 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 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 new-line is specified by \n.  The default data
    keywords are:

                     ":Dt:\t:DL:\nMRs:\n:MR:COMMENTS:\n:C:"

 Examples

    prs -d"Users and/or user IDs for :F: are:\n:UN:" s.file

    may produce on the standard output:

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

    prs -d"Newest delta for pgm :M:: :I: Created :D: By :P:" -r s.file

    may produce on the standard output:

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

    As a special case:  prs s.file may produce on the standard output for
    each delta table entry of the ``D'' type. For example:

       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

    The only option allowed to be used with the special case is -a.
