Many times, when you are navigating through folders using a file browser and after reaching somewhere deep into the hierarchy you realize that a terminal is required. Of course, it hardly takes any time to open a terminal and reach that location, but aren't computers all about getting things done as quickly and comfortably as possible? So, here is a nautilus extension for all such users - "nautilus-open-terminal".
This extension adds an option in the Right-Click Menu to open a terminal on the fly at that folder location. This way you don't have to go through the trouble of opening a terminal and entering the address. This comes in handy a lot.
[shredder12]$ sudo apt-get install nautilus-open-terminal #for Ubuntu/Debian based distros
[shredder12]$ su -c "yum install nautilus-open-terminal" #for fedora/RedHat based distros
The results might not appear instantly. You may have to restart nautilus(close & re-open) to get things done.
