ident


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
       RCS'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 $XConsortium$.

       The pattern normally requires a colon and a space immediately after the
       keyword and a space immediately before the terminating $, but for  Sub-
       version  1.2  (and  later) compatibility, ident will also recognize the
       pattern $keyword:: text $ (i.e., two colons and a space) and  the  pat-
       tern  $keyword:: text #$  (likewise, with a hash before the terminating
       $).  These are the fixed-width keyword syntax.  To summarize, the three
       recognized patterns are:

              $keyword: text $
              $keyword:: text $
              $keyword:: text #$

KEYWORDS
              sion  number,  the date and time, the author, the state, and the
              locker (if locked).

       $Id$   Same as $Header$, except that  the  RCS  file  name  is  without
              directory components.

       $Locker$
              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 RCS file name without directory components.

       $Revision$
              The revision number assigned to the revision.

       $Source$
              The full RCS file name.

       $State$
              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
              \        \\
