If you have a filename, then you probably already have some "relative" path to that filename, even if we're making the assumption that you're working from the current directory. In this case, File::Spec will do the job for you with its rel2abs function: `$abs_path = File::Spec->rel2abs($filename);` [download] If you have a file but have no idea where it's located, you might want to use File::Find.

Add this to the top of your code: `use Cwd;` [download] Then you can just: `$thisdir = cwd();` [download] This gets the directory the "safest" way. If you are definitely on unix, however, you can simply say: $thisdir = `pwd`; [download] which is usually what Cwd does on unix systems. It has a few other options, such as fastcwd() and getcwd() but they are not used much. You can grab the name of the script itself by looking in $0 or even __FILE__. If you are doing it through the web, check out the environment variable 'SCRIPT_FILENAME' `$pwd = $ENV{'SCRIPT_FILENAME'};` [download]	[reply] [d/l] [select]
