Freak out no more...here's how to use the terminal/command line! Using the terminal is EASY, and more importantly, it's a HUGE part of being a web developer these days. If you avoid the terminal, it will only hold you back. This tutorial will teach you how to use the command line in a few easy steps. You'll be comfortable in no time.

ls - list files
cd {directory name} - change directory
cd / - go to root (top) directory
cd ~ - go to user home directory
cd .. - go up a level
mkdir {file name} - make a directory
touch {filename} - create an empty file
rm {filename} - remove a file
rm -r {directory name} - remove a directory and all files within
mv {filename} {new filename} - rename a file or folder
open {filename} - open file in default program
open {filename} -a "{program name}" - open file in specific application
open . - open current directory

HOT KEYS
Command+k - clear the terminal screen
Tab - autocomplete (if more than one files match, nothing happens, you will need to add more characters)
Up/Down Arrows - previous commands
