| − | =Algorithms and Data Structures= | + | = Source Control = |
| | + | It is a good idea to use source control when developing software, and is necessary when you are developing in a group or professionally. When working on assignments or course projects it is the best practice to use a private repository so other students cannot copy your work. Git is the industry standard for source control. Here are some resources to use to learn Git. |

| − | ==System Setup==
| |
| − | Next, you need to have a Linux system that you can use.
| |
| − | | |
| − | ===ISU CS Account===
| |
| − | If you are a student in a CS course at ISU you will be given an account on the CS linux systems (see [[CS Accounts and CS Lab Computers]]).
| |
| − | | |
| − | ===Linux on Your Computer===
| |
| − | You can also download and install [https://www.virtualbox.org/wiki/Downloads VirtualBox] on your computer, download a Linux install image (e.g., [https://www.ubuntu.com/download/desktop Ubuntu Linux]), and then [https://www.instructables.com/id/How-to-install-Linux-on-your-Windows/ install Linux into your virtual box].
| |
| − | | |
| − | ====Mac OS X====
| |
| − | You can also use a Mac OS X computer - most (but not all) commands are the same on Linux and Mac OS X. On Mac OS X, to get to the terminal you click on Finder, then Applications, then Utilities, then Terminal.
| |
| − | | |
| − | ==Try it Out==
| |
| − | Once you have your Linux system to try out, open up the terminal (also called the shell, or command prompt), and you are ready to try out some commands. '''Note that all commands in Linux are case-sensitive. Also, _ is different than -, and ' is different than ".'''
| |
| − | | |
| − | ===System Information, Part 1===
| |
| − | The following are some commands to print information about the system.
| |
| − | * uptime - how long since last system reboot
| |
| − | * df - information about disk free space
| |
| − | * whomi - which user is currently logged in on the terminal
| |
| − | * hostname - what computer are you currently running commands on
| |
| − | * pwd - which directory are you inside of
| |
| − | * clear - clear the terminal screen
| |
| − | Here is an example session from running on the CS server using all of these commands.
| |
| − | <pre>
| |
| − | cs299@cs:~> uptime
| |
| − | 09:00:45 up 56 days, 19:35, 3 users, load average: 0.32, 0.31, 0.32

| − | ===Text Editors, Part 1===
| |
| − | One thing programmers need to do is edit text files. The text files could be your programs, or they could be data files. There are many different text editors that are normally installed on Linux systems. The most popular are - vim, emacs, nano.
| |
| − | | |
| − | nano is among the easiest text editors to use, so let's get you started using nano. You first need to be logged into Linux and open a terminal. Type the following
| |
| − | <pre>
| |
| − | nano hello.txt
| |
| − | </pre>
| |
| − | You will now be running the nano editor and editing a file named hello.txt. Note that the interface is '''completely text-based'''. There is nothing for you to click on. Instead of clicking on menus, you have control codes that you can type to save, close, etc. The bottom of the screen lists the control codes that you can use. Each control code is typed by holding down the control key on your keyboard and then pressing a letter.
| |
| − | | |
| − | For example, hold down control and press x to Exit nano. You can type nano hello.txt again to open the nano editor again.
| |
| − | | |
| − | Now type some text, for example "Hello World". You can save your file by holding down control and pressing o. When you do this, nano prompts you to ask what the name of the file should be; you can leave it alone as hello.txt and press enter. Your file is now saved! You can type more into your hello.txt file if you wish. Use the arrow keys on your keyboard to move around inside of your text file. When you are done editing, use control-o to write out (save) your file, and then use control-x to exit nano.

| |
| − | ===Files and Directories, Part 1===
| |
| − | With the terminal you can create, copy, move, and delete files and directories. The following are the most important commands to do this.
| |
| − | * cd - change directory
| |
| − | * mkdir - make a new directory
| |
| − | * ls - list directory contents
| |
| − | * cp - copy files
| |
| − | * rm - remove files (be careful, there is no recycle bin or trash - once you delete, it's gone)
| |
| − | * rmdir - remove directory
| |
| − | * nano - simple text editor
| |
| − | And here is a transcript of the use of these commands on the CS server.
| |
| − | <pre>
| |
| − | cs299@cs:~> pwd
| |
| − | /u1/class/cs299
| |
| − | cs299@cs:~> mkdir new-dir1
| |
| − | cs299@cs:~> mkdir new-dir2
| |
| − | cs299@cs:~> nano hello.txt
| |
| − | cs299@cs:~> ls
| |
| − | bin/ hello.txt new-dir1/ new-dir2/ proto/
| |
| − | cs299@cs:~> cp hello.txt new-dir1
| |
| − | cs299@cs:~> cp hello.txt new-dir2/hello2.txt
| |
| − | cs299@cs:~> ls new-dir1
| |
| − | hello.txt
| |
| − | cs299@cs:~> ls new-dir2
| |
| − | hello2.txt
| |
| − | cs299@cs:~> mv new-dir2 new-dir3
| |
| − | cs299@cs:~> ls
| |
| − | bin/ hello.txt new-dir1/ new-dir3/ proto/
| |
| − | cs299@cs:~> rm hello.txt
| |
| − | cs299@cs:~> ls
| |
| − | bin/ new-dir1/ new-dir3/ proto/
| |
| − | cs299@cs:~> rmdir new-dir3
| |
| − | rmdir: failed to remove 'new-dir3': Directory not empty
| |
| − | cs299@cs:~> rm new-dir3/hello2.txt
| |
| − | cs299@cs:~> rmdir new-dir3
| |
| − | cs299@cs:~> ls
| |
| − | bin/ new-dir1/ proto/
| |
| − | </pre>
