How about the following:
if find /some/dir/ -maxdepth 0 -empty | read; then echo "huzzah"; fi
This way there is no need for generating a complete listing of the contents of the directory. The `read` is both to discard the output and make the expression evaluate to true only when something is read (i.e. `/some... |

a more low-level appproach is [redland][1], which provides bindings to a lot of languages like Perl, PHP, Python and Ruby. redland itself is written in C. i have scripted with it in ruby to provide a simple webservice with a rdf backend instead of a classic database.

try
string.match( /[$]chkChecked$/ )
alternatively, you could try
string.match( /[^a-zA-Z0-9]chkChecked/ )
( Also, make sure your using <code>//</code> around your regex, otherwise you might be matching using string literals. Not obvious tho without a larger code snippet ) |
It looks like it should work.
There's a good [Javascript Regex Tester](http://www.regular-expressions.info/javascriptexample.html) that also says it matches. |
