One of your goals as a Linux user should be reducing the amount of characters you have to type to accomplish your goals. The original developers of Unix were strong believers in that conceptthat's why you enter ls instead of list and mkdir instead of makedirectory.

The commands you've learned about in this chapterhistory and aliasboth aid in that process. Tired of typing a long and complicated command? Reference it with history, or create an alias for it. Either way, you'll save keystrokes, and your keyboard (and, more importantly, your hands and wrists) will thank you for it.
