If you want it to work on linux (Gnome), I'd replace the bottom line with:

 if [ "`which gnome-www-browser`" != "" ]; then
     gnome-www-browser $URL
 else
     open $URL
 fi

Done! Thanks

You might be happier with life if you didn't write things in Bash.

Just sayin'. >_>

Ryan, haven't you been writing PHP the past 2 weeks? Just sayin'

Exactly, I know pain when it's staring me in the face, so my word is legit. ;0
