| # Command Line Basics | ||
|
|
||
| Using Tessel is just like web development. But if | ||
| you're not familiar with web development, you might want | ||
| to take a minute or two to get comfortable with some key | ||
| tools of the trade: the command line (the "terminal", | ||
| where you execute commands) and the text editor, where | ||
| you will work on and save your programs. | ||
|
|
||
| Select the operating system you are working on. | ||

| Open up the application on your computer called “Terminal” by pressing ⌘ + SPACE and typing “Terminal”. | ||
|

|
|
||
| You can use the terminal to write commands to your computer (this is the “command line”). Let’s try it out! | ||
|
|
||
| In your terminal, type | ||
|
|
||
| `ls` | ||
|
|
||
| and hit enter. | ||
|
|
||
| The `ls` command, short for “list”, tells your computer to list all of the file names for the folder you’re in. Your list of files probably includes “Desktop” and “Documents”, among others. | ||
|
|
||
| Let’s try another command: type | ||
|
|
||
| `cd Documents` | ||
|
|
||
| and hit enter. | ||
|
|
||
| You are now in the Documents folder; `cd` means “change directory”. If you try `ls` again, you should see the contents of your Documents folder listed out. If you want to compare, open up Finder and look in Documents to see the same files. | ||
|
|
||
| Let’s get back to the folder we were in before: `cd ..` | ||
|
|
||
| You changed directory again! `ls` | ||
| to see what we have here. You’re back where you started! The `..` after `cd` tells it to go up one folder in the directory. | ||
|
|
||
| Ok, now you're a cool hacker who can use the terminal (or "console") to write in the command line. | ||
|
|
||
| (If you want to learn more commands, there are a whole bunch of them <a href="http://ss64.com/bash/" target="1">here</a>. I recommend `pwd`, `open`, `mkdir`, `touch`, `mv`, and `cp`.) | ||

| ### Text Editors | ||
|
|
||
| You will also need a text editor to save your JavaScript files. This means a plaintext editor, not a Word document. | ||
|
|
||
| Here are some good options: | ||
|
|
||
| * [Sublime Text](http://www.sublimetext.com/) | ||
| * [Atom](https://atom.io/) | ||
| * [Notepad++](http://notepad-plus-plus.org/) | ||
|

|
|
||
| Typically, directions that belong in the command line | ||
| are one line, whereas longer scripts, such as anything in | ||
| JavaScript, should be typed into the text editor and | ||
| saved, then run through the command line. | ||
|
|
||
| In the context of this tutorial, things that should be | ||
| run in the command line look `like this` | ||
|
|
||
| And scripts that should be saved in the text editor | ||
| will look | ||
|
|
||
| <pre class="prettyprint"> | ||
| <code>like this</code> | ||
