Opening current directory from a terminal onto a file browser?

My current directory is buried deep in multiple subfolder layers from my home directory. If I want to open this directory in a *gui-based* file browser, I have to double click folder after folder to reach it. This is very time consuming. On the other hand, with very few key strokes and several times hitting the tab button, it is very easily reachable via a terminal. I want to know if there is a way to open the current directory in a terminal onto a a file browser. What is the command to do this? For reference, I have an ubuntu system, but I'd like to know what the commands are across the various distributions of linux.
