Ruby Scripts Location

Doug Bromley

Hi All

I know this should be very simple but I can't for the life of me find
the answer using Pickaxe or Google.

I want to be able to access the location/path of the currently
executing Ruby script. I thought it was a global variable "$" but
looking at the lists I've seen I can't find it.

Your help would be much appreciated.

Thanks.

Doug

$0 is probably what you want. Use File.expand_path on it to get the full
path.

$0, or __FILE__ in the main script file.
