IDENT(1)							      IDENT(1)

NAME
       ident - identify	RCS keyword strings in files

SYNOPSIS
       ident [ -q ] [ -V ] [ file ... ]

DESCRIPTION
       ident searches for all instances	of the pattern $keyword: text $	in the
       named files or, if no files are named, the standard input.

       These patterns are normally inserted automatically by the  RCS  command
       co(1), but can also be inserted manually.  The option -q	suppresses the
       warning given if	there are no patterns in a file.  The option -V	prints
       ident's version number.

       ident works on text files as well as object files and dumps.  For exam-
       ple, if the C program in	f.c contains

	      #include <stdio.h>
	      static char const	rcsid[]	=
		"$Id: f.c,v 5.4	1993/11/09 17:40:15 eggert Exp $";
	      int main() { return printf("%s\n", rcsid)	== EOF;	}

       and f.c is compiled into	f.o, then the command

	      ident  f.c  f.o

       will output

	      f.c:
		  $Id: f.c,v 5.4 1993/11/09 17:40:15 eggert Exp	$
	      f.o:
		  $Id: f.c,v 5.4 1993/11/09 17:40:15 eggert Exp	$

       If a C program defines a	string like rcsid above	but does not  use  it,
       lint(1)	may  complain,	and  some  C  compilers	will optimize away the
       string.	The most reliable solution is to  have	the  program  use  the
       rcsid string, as	shown in the example above.

       ident finds all instances of the	$keyword: text $ pattern, even if key-
       word is not actually an RCS-supported keyword.  This gives you informa-
       tion about nonstandard keywords like $XConsortium$.

KEYWORDS
       Here  is	the list of keywords currently maintained by co(1).  All times
       are given in Coordinated	Universal Time (UTC, sometimes called GMT)  by
       default,	 but  if  the  files were checked out with co's	-zzone option,
       times are given with a numeric time zone	indication appended.

       $Author$
	      The login	name of	the user who checked in	the revision.

       $Date$ The date and time	the revision was checked in.

       $Header$
	      A	standard header	containing the full pathname of	the RCS	 file,
	      the  revision  number, the date and time,	the author, the	state,
	      and the locker (if locked).

       $Id$   Same as $Header$,	except that the	 RCS  filename	is  without  a
	      path.

       $Locker$
	      The login	name of	the user who locked the	revision (empty	if not
	      locked).

       $Log$  The log message supplied during checkin.	For ident's  purposes,
	      this is equivalent to $RCSfile$.

       $Name$ The symbolic name	used to	check out the revision,	if any.

       $RCSfile$
	      The name of the RCS file without a path.

       $Revision$
	      The revision number assigned to the revision.

       $Source$
	      The full pathname	of the RCS file.

       $State$
	      The  state assigned to the revision with the -s option of	rcs(1)
	      or ci(1).

       co(1) represents	the following characters in keyword values  by	escape
       sequences to keep keyword strings well-formed.

	      char     escape sequence
	      tab      \t
	      newline  \n
	      space    \040
	      $	       \044
	      \	       \\
