The biggest downfall to nearly any new Linux user, is they treat it like Windows. I prefer to use the command line for any larger scale jobs that I may do, as its easier to chain a few commands together to get a lot of work done vs having to click something, change it, move to the next file, and so on and so forth. The way I learned Linux, was I simply quit using Windows. Im now running Windows for the first time in 4 years, but now I can effectively use both OSes with ease. The first 2 months were pure hell, but I made it. Google is an excellent resource on Linux. The best search query you could use would involve "how to [perform a certain task] in [the distro youre running]." Each distro has extensive documentation on how to do what it is you need. If you want to dabble in the command line, dont forget the man pages. The man pages are manuals for each program that can be run from the command line. To access the man page for a certain program, simple type
and youll have a well written description on how to get your program to do what you want

. Oh yeah, forgot to add instead of using terminal (command line) emulators, just use the TTYs. CTRL + ALT + F2 thru F6. You can have up to 5 terminals running at once via the TTYs. Bring up your man page in one, and input your command in another

. To get back to the GUI, press CTRL + ALT + F7.
