Ok I'm pretty illeterate when it comes to the terminal. I'm using linux so I probably know a little more than the average joe. I've been messing with the terminal emulator to try and get a little more comfortable with it. I've noticed, that inspite of this being a linux system some commands are different or something. For example "file" doesn't seem to work. I always get permission denied. What are the differences between term emulator and terminal in ubuntu and can I find a tutorial somewhere that will teach me more about using android terminals?
