 # Terminal
 
-The terminal (or 'command-line') on a computer allows a user a great deal of control over their system (or in this case, Pi!). Users of Windows may already have come across `Command Prompt` or `Powershell` and Mac OS users may be familiar with `Terminal`. All of these tools allow a user to directly manipulate their system through the use of commands. These commands can be chained together and/or combined together into complex scripts that can be potentially more efficient at completing tasks than much larger traditional software packages.

 ## Navigating and browsing your Pi
 
 One of the key aspects of using a terminal is being able to navigate your file system. Firstly, run the following command: `ls -la`. You should see something similar to:
 
 ![](images/lsresult.png)
 
-The `ls` command lists the contents of the directory that you are currently in (your present working directory). The `-la` component of the command is what's known as a 'flag', these modify the command that's being run. In this case the `l` displays the contents of the directory in a list, showing data such as their sizes and when they were last edited, and the `a` displays all files, including those beginning with a . - known as 'dotfiles'. Dotfiles usually act as configuration files for software and as they are written in text, they can be modified by simply editing them.

Dotfiles usually act as configuration files for software and as they are written in text, they can be modified by simply editing them. 
 
 In order to navigate to other directories the change directory command, `cd`, can be used. You can specify the directory that you want to go to by either the 'absolute' or the 'relative' path. So if you wanted to navigate to the `python_games` directory, you could either do `cd /home/pi/python_games` or just `cd python_games` (if you are currently in `/home/pi`). There are some special cases that may be useful: `~` acts as an alias for your home directory, so `~/python_games` is the same as `/home/pi/python_games`; `.` and `..` are aliases for the current directory and the parent directory respectively, e.g. if you were in `/home/pi/python_games`, `cd ..` would take you to `/home/pi`.

-Now, save this with the name `fun-script`. Before you can run it you must first make it executable, this can be done by using the change mode command `chmod`. Each file and directory has it's own set of permissions that dictate what a user can and can't do to it. In this case, by running the command `chmod +x fun-script`, the file `fun-script` will now be executable. You can then run it by typing `./fun-script` (assuming that it is in your current directory).
