Part II VI Text Editor The VI Text Editor • Vi (“vee eye”) is a basic but powerful screen based (no fancy GUI) text editor. • One of many available, but you will get to use it for your first tutorial! • Vi is a screen based editor which operates in one of two modes: – Command Mode – Text Entry Mode 5

Command Mode • vi has no GUI so all operations are performed from keyboard. • Commands are typed from keyboard, for example: – dw – deletes the word at the cursor – dl – deletes the current line – :wq – save file and quit. • You cannot type text while in Command Mode. Text Entry Mode • Whatever you type while in Text Entry Mode appears in your document. • To switch to text input mode you use: – i - will switch to text mode and allow typing at cursor. – a – will switch to text mode and allow typing at character immediately after cursor. • You can use arrows keys to navigate while in text entry mode. • The ‘Esc’ key will return you to Command Mode. 6

Part III: GCC Compile Introduction to GCC • For this tutorial you will be compiling a very simple C program. • GCC takes one (or more) C source files and generates an executable program that you can execute from the terminal. • For the tutorial you will be expected to generate a program the prints “Hello World”. 7
