sccs-prs(1) User Commands sccs-prs(1)

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

/usr/ccs/bin/prs 
[-ael] 
[-c
date-time] 
[-d
dataspec]


    [-q
[nsedelim]] 
[-r
sid]


    [-X
extended-options] 
[-N
bulk-spec] 
s.filename...

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

The output is based on data from the s.files that is first converted into a binary format and later converted back into text.

If a directory name is used in place of the s.filename argument, the prs command applies to all s.files in that directory. Unreadable s.files produce an error; processing continues 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.

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.

A date-time specification in the form:

yyyy/[mm[dd[hh[mm[ss]]]]]

refers to a 4-digit year and allows to specify a year outside the range 1969−2068.

-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 NEWLINE 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.

-q[nsedelim]
Enable NSE mode. If NSE mode is enabled, several NSE related extensions may be used. In this release, the value of nsedelim is ignored.

This option is an undocumented SUN extension that does not exist in historic sccs implementations.

-Nbulk-spec
Processes a bulk of SCCS history files. This option allows to do an efficient mass processing of SCCS history files.

The bulk-spec parameter is composed from an optional list of flag parameters followed by an optional path specifier.

The following flag types are supported:

++
If bulk-spec is preceded by a `++', prs(1) expects to process filenames that are prepended by a plus sign, the related SID and another plus sign following the form:

+sid+filename

This permits each file to be retrieved with an individual SID.

space
This is a placeholder dummy flag that allows to use a prepared string for the -N option and to replace the space character by one of the supported flags on demand.

The following path specifier types are supported:

-N
The file name parameters to the prs command are not s.filename files but the names of the g-files. The s.filename names are automatically derived from the g-file names by prepending s. to the last path name component. Both, s.filename and the g-file are in the same directory.
-Ns.
The file name parameters to the prs command are s.filename files. The the g-files names are automatically derived by removing s. from the beginning of last path name component of the s.filename. Both, s.filename and the g-file are in the same directory.
-Ndir
The file name parameters to the prs command are not s.filename files but the names of the g-files. The s.filename names are put into directory dir, the names are automatically derived from the g-file names by prepending dir/s. to the last path name component.
-Ndir/s.
The file name parameters to the prs command are s.filename files in directory dir. The the g-files names are automatically derived by removing dir/s. from the beginning of last path name component of the s.filename.

A typical value for dir is SCCS.

In order to overcome the limited number of exec(2) arguments, it is recommended to use `−' as the file name parameter for prs(1) and to send a list of path names to stdin.

This option is a SCHILY extension that does not exist in historic sccs implementations.

-Xextended-options
Specify extended options. The argument extended-options may be a comma separated list of extended option names.

The following extended options are supported, they may be abbreviated as long ad the abbreviation is still unique. Options with parameter may not be abbreviated.

0
When reading filenames from stdin, triggered by a file name argument `-', the filename separator is a null byte instead of a newline. This allows to use long lists with arbitrary filenames.
help
Print a short online help for available options.

The -X option is a SCHILY extension that does not exist in historic sccs implementations.

-V
-version
--version
Prints the prs version number string and exists.

This option is a SCHILY extension that does not exist in historic sccs implementations.

Usage of prs is described below.

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:

Example 1 Displaying delta entries



The following command:





  




example% 
/usr/ccs/bin/prs -e -d":I:\t:P:" program.c







produces:





  




1.6	username
1.5	username
...















See environ(5) for descriptions of the following
    environment variables that affect the execution of prs(1):
    LANG, LC_ALL, LC_COLLATE, LC_CTYPE,
    LC_MESSAGES, and NLSPATH.





  
SCCS_NO_HELP

  
If set, prs(1) will not automatically call help(1) with the
      SCCS error code in order to print a more helpful error message. Scripts
      that depend on the exact error messages of SCCS commands should set the
      environment variable SCCS_NO_HELP and set LC_ALL=C.
    

  










The following exit values are returned:





  
0

  
Successful completion.
    

  

  
1

  
An error occurred.

SCCS history file, see sccsfile(4).
    

    

  

  
/tmp/pr?????

If the file dump.core exists in the current directory and a fatal

The SCCS suite was originally written by Marc J. Rochkind at Bell Labs in
  1972. Release 4.0 of SCCS, introducing new versions of the programs
  admin(1), get(1), prt(1), and delta(1) was
  published on February 18, 1977; it introduced the new text based
  SCCS v4 history file format (previous SCCS releases used
  a binary history file format). The SCCS suite was later maintained by
  various people at AT&T and Sun Microsystems. Since 2006, the SCCS
  suite is maintained by Joerg Schilling.








A frequently updated source code for the SCCS suite is included in the
  schilytools project and may be retrieved from the schilytools
  project at Sourceforge at:


   http://sourceforge.net/projects/schilytools/


The download directory is:
