ident

ident(1)																  ident(1)

NAME

       ident - identify files

SYNOPSIS

       ident [-q] [file...]

DESCRIPTION

       ident searches for all occurrences of the pattern $keyword:...$ in the named files or, if no file name appears, 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.

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

       char rcsid[] = "$Id: ident.1,v 1.1.10.2 1999/08/13 19:58:10 Colin_Walters Exp $";

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

       # ident	f.c  f.o

       will output

       f.c:
	 $Id: ident.1,v 1.1.10.2 1999/08/13 19:58:10 Colin_Walters Exp $ f.o:
	 $Id: ident.1,v 1.1.10.2 1999/08/13 19:58:10 Colin_Walters Exp $
