       prs - print an SCCS file (DEVELOPMENT)


       prs [-a][-d dataspec][-r[SID]] file...

       prs [ -e| -l] -c cutoff [-d dataspec] file...

       prs [ -e| -l] -r[SID][-d dataspec]file...


       The  prs  utility  shall  write to standard output parts or all of an SCCS file in a user-
       supplied format.


       The prs utility shall conform to the  Base  Definitions  volume  of  IEEE Std 1003.1-2001,
       Section 12.2, Utility Syntax Guidelines, except that the -r option has an optional option-
       argument. This optional option-argument cannot be presented as a  separate  argument.  The
       following options shall be supported:

       -d  dataspec
              Specify the output data specification. The dataspec shall be a string consisting of
              SCCS file data keywords (see Data  Keywords  )  interspersed  with  optional  user-
              supplied text.

              Specify  the  SCCS  identification string (SID) of a delta for which information is
              desired. If no SID option-argument is specified,  the  SID  of  the  most  recently
              created delta shall be assumed.

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

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

       -c  cutoff
              Indicate the cutoff date-time, in the form:


       For  the  YY  component,  values  in  the  range [69,99] shall refer to years 1969 to 1999
       inclusive, and values in the range [00,68] shall refer to years 2000 to 2068 inclusive.

              It is expected that in a future version of IEEE Std 1003.1-2001 the default century
              inferred  from  a  2-digit  year  will  change.  (This  would apply to all commands
              accepting a 2-digit year as input.)

       No changes (deltas) to the SCCS file that were created after the  specified  cutoff  date-
       time  shall  be  included in the output. Units omitted from the date-time default to their
       maximum possible values; for example, -c 7502 is equivalent to -c 750228235959.

       -a     Request writing of information for both removed-that is, delta type= R  (see  rmdel
              )- and existing-that is, delta type= D,- deltas. If the -a option is not specified,
              information for existing deltas only shall be provided.


       The following operand shall be supported:

       file   A pathname of an existing SCCS file or a directory. If file is a directory, the prs
              utility shall behave as though each file in the directory were specified as a named
              file, except that non-SCCS files (last component of the  pathname  does  not  begin
              with s.) and unreadable files shall be silently ignored.

       If  exactly  one  file  operand appears, and it is '-' , the standard input shall be read;
       each line of the standard input shall be taken to be the  name  of  an  SCCS  file  to  be
       processed.  Non-SCCS files and unreadable files shall be silently ignored.


       The  standard  input  shall be a text file used only when the file operand is specified as
       '-' . Each line of the text file shall be interpreted as an SCCS pathname.


       Any SCCS files displayed are files of an unspecified format.


       The following environment variables shall affect the execution of prs:

       LANG   Provide a default value for the internationalization variables that  are  unset  or
              null.  (See  the  Base  Definitions  volume  of  IEEE Std 1003.1-2001, Section 8.2,
              Internationalization Variables for the precedence of internationalization variables
              used to determine the values of locale categories.)

       LC_ALL If  set  to  a  non-empty  string  value,  override  the  values  of  all the other
              internationalization variables.

              Determine the locale for the interpretation of sequences of bytes of text  data  as
              characters  (for  example,  single-byte  as  opposed  to  multi-byte  characters in
              arguments and input files).

              Determine the locale that should be used to  affect  the  format  and  contents  of
              diagnostic messages written to standard error.

              Determine the location of message catalogs for the processing of LC_MESSAGES .




       The  standard  output  shall be a text file whose format is dependent on the data keywords
       specified with the -d option.

   Data Keywords
       Data keywords specify which parts of an SCCS file shall be retrieved and output. All parts
       of  an  SCCS file have an associated data keyword. A data keyword may appear in a dataspec
       multiple times.

       The information written by prs shall consist of:

        1. The user-supplied text

        2. 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  shall either be simple ( 'S' ), in which keyword
       substitution is direct, or multi-line ( 'M' ).

       User-supplied text shall be any text other than recognized data keywords.  A  <tab>  shall
       be  specified  by  '\t'  and  <newline> by '\n' . When the -r option is not specified, the
       default dataspec shall be:


       and the following dataspec shall be used for each selected delta:

       The following sections are informative.




        1. The following example:

              User Names for s.file are:

        2. The following example:

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

       might write to standard output:

              Delta for pgm main.c: 3.7 - 77/12/01 By cas

        3. As a special case:

           prs s.file

       might write to standard output:

              this is the comment line for s.file initial delta
              <blank line>

       for  each  delta  table  entry of the D type. The only option allowed to be used with this
       special case is the -a option.
