4. Connecting to the University Linux Server
We use an SSH client to make a network connection to a remote computer (basically text-based remote desktop)
Any SSH client should work (hint for mac/linux users)
Use SSH to connect to: login.cs.auckland.ac.nz
Login using your UPI and password
You can access the Linux server from anywhere

8. Basic Linux Commands
We will not use the Linux command-line very much, but it is important to know a few basic commands
ls list files and directories
mkdir make directory
cd change directory
pwd print working directory

9. More Basic Linux Commands
…and a few additional commands
cp copy file
mv move file (also used to rename files)
rm remove file
rmdir remove directory
clear clear screen
…many more! Feel free to explore.

10. Nano
Nano is a simple text editor you can use to write code while connected to the Linux server. There is a basic tutorial HERE. You can start Nano by typing the command: nano Or you can edit a specific file by typing it with the command: nano myfile.txt

11. GCC
GCC is the C language compiler we will be using. Only code which compiles using GCC version (the version found on the Linux server) will be awarded marks for assignment 2. There is a basic tutorial HERE. This command will turn your code into a program called a.out: gcc mycode.c Or you can name your program by typing a name with the command: gcc mycode.c –o myprogram Note: In Linux, compiled programs traditionally have no extension.

12. cplusplus.com Reference site for C and C++
Provides information on all standard functions
Think of it as the LC-3 Reference, but for C. (have it open when you are working)
Great place to find example code!
Also en.cppreference.com/w/c
