.SH SYNOPSIS
.B ident
[
.B \-q
] [
.I file
\&.\|.\|. ]
.SH DESCRIPTION
.B ident
searches for all occurrences of the pattern
.BI $ keyword : .\|.\|. $
in the named files or, if no file name appears, the standard input.
.PP
These patterns are normally inserted automatically by the \*r command
.BR co (1),
but can also be inserted manually.
The option
.B \-q
suppresses
the warning given if there are no patterns in a file.
.PP
.B ident
works on text files as well as object files and dumps.
For example, if the C program in
.B f.c
contains
.IP
\f3char rcsid[] = \&"$\&Id: f.c,v \*(iD $\&";\fP
.LP
and
.B f.c
is compiled into
.BR f.o ,
then the command
.IP
.B "ident  f.c  f.o"
.LP
will output
.nf
.IP
.ft 3
f.c:
    $\&Id: f.c,v \*(iD $
f.o:
    $\&Id: f.c,v \*(iD $
.ft
.fi
