Re: help using the command line
You can also drag files and folders to the terminal to fill in their paths.
For instance, type 'cd ' and don't hit Enter. Drag the Downloads folder to the terminal and its full path will appear. Press Enter and you will change directory to the folder you dragged in.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
