sccs-prs(1)




NAME

     sccs-prs, prs - display selected portions of an SCCS history


SYNOPSIS

     /usr/ccs/bin/prs [-ael] [-cdate-time]  [-ddataspec]  [-rsid]
     s.filename...


DESCRIPTION

     The prs utility displays part or all of the SCCS  file  (see
     sccsfile(4)) in a user supplied format.

     If a directory name is used in place of the s.filename argu-
     ment,  the prs command applies to all s.files in that direc-
     tory. Unreadable s.files produce an error;  processing  con-
     tinues  with  the  next file (if any). The use of `-' as the
     s.filename argument indicates that the names of files are to
     be read from the standard input, one s.file per line.


OPTIONS

     In the absence of options,  prs  displays  the  delta  table
     (version log). In the absence of -d, or -l, prs displays the
     entry for each delta indicated by the other options.

     -a    Includes all deltas, including those marked as removed
           (see sccs-rmdel(1)).

     -e    Requests information for all  deltas  created  earlier
           than,  and  including,  the delta indicated with -r or
           -c.

     -l    Requests information  for  all  deltas  created  later
           than,  and  including,  the delta indicated with -r or
           -c.

     -cdate-time
           Either options -e or -l must be used with this option.
           -cdate-time displays information on the deltas checked
           in either prior to and including  the  date  and  time
           indicated  by  the  date-time argument (option -e); or
           later than and including the date and  time  indicated
           (option -l). date-time takes the form:

           yy[mm[dd[hh[mm[ss]]]]]

           Units omitted from the indicated date and 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
           components.   If  white-space  characters  occur,  the
           date-time  specification  must be quoted. Values of yy
           in the range 69-99 refer  to  the  twentieth  century.
           Values in the range of 00-68 refer to the twenty-first
           century.

     -ddataspec
           Produce a  report  according  to  the  indicated  data
           specification.  dataspec  consists  of a (quoted) text
           string that includes embedded  data  keywords  of  the
           form:  `:key:' (see Data Keywords, below). prs expands
           these keywords in the output it produces. To specify a
           TAB character in the output, use \t; to specify a NEW-
           LINE in the output, use \n.

     -rsid Specifies the SCCS delta ID (SID)  of  the  delta  for
           which information is desired. If no  SID is specified,
           the most recently created delta is used.


USAGE

     Usage of prs is described below.

  Data Keywords
     Data keywords specify which parts of an SCCS file are to  be
     retrieved.  All parts of an SCCS file (see sccsfile(4)) have
     an associated data keyword. A data keyword  may  appear  any
     number  of  times  in  a  data specification argument to -d.
     These data keywords are listed in the table below:

     Keyword             Data Item             File Section*               Value                Format**
