Why Use the Command Line • Makes you faster • Powerful • Concise • Sometimes it’s the only way to run certain programs

Common commands for getting around in your directories • cd – Change directory – .. lets you go up one level • ls – List contents of directory – Command for windows is dir • pwd – Shows directory you are currently in

Moving around on the command line • Ctrl + Left/Right arrow – Jumps between arguments in your – Option instead of Ctrl on Mac • Ctrl + U clears the line • Ctrl + A or the Home key takes you to the front of the line • Ctrl + E or the End key takes you to the end of the line

Helpful tips • Tab – Autocompletes directory and/or file name • Up/down arrow – Cycles through commands you’ve previously inputted • clear • Make your terminal beautiful by customizing your ~/.bashrc or ~/.bash_profile

If you are on Windows… • Consider using Cygwin • /? after any command will show help and optional flags • To switch between different drives simply type : (e.g - e: will switch to the E drive)
