       ident - identify RCS keyword strings in files

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

       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 example, if the  C  pro-
       gram 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

		  $Id: f.c,v 5.4 1993/11/09 17:40:15 eggert Exp $
		  $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 com-
       plain, 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 keyword is not actually
       an RCS-supported keyword.  This gives you  information  about  nonstandard  keywords  like

       Here  is the list of keywords currently maintained by co(1).  All times are given in Coor-
       dinated 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

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

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

	      A standard header containing the full pathname of the RCS file, the  revision  num-
	      ber, 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.

	      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.

	      The name of the RCS file without a path.

	      The revision number assigned to the revision.

	      The full pathname of the RCS file.

	      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
	      \        \\
