searching a file

I have written a perl program to examine a log file...

The line that i think is causing the trouble is:

$regEx = "\w+ - - \[[\w\s]*\ $docRegEx";

(if statements to check whether that line is in the file)

The above line is supposed to match the document requested in the logfile. For example a line of the logfile might look like this:

quark - - [24/Oct/1999:04:40:10 +0600] "GET /images/black/off.GIF HTTP/1.0" 404 -

And if $docRegEx was set to /images/black/off.GIF it should match it. The problem is it doesn't. Any idea whats wrong with it?

thanks in advance,
Nick

Try this out:

#!/usr/bin/perl

$docRegEx = '/images/black/off.GIF';
$line = 'quark - - [24/Oct/1999:04:40:10 +0600] "GET /images/black/off.GIF HTTP/1.0" 404 - ';
if ($line =~ /^[\w -]+\[[^\]]+\] "\w+ $docRegEx/) {
print "Match!\n";
} else {
print "No Match!\n";
}

exit;

It looks like the ending bracket was missing (the one after the number 600).
