+sudo
+-------
+
+`sudo` stands for *Super User DO* and allows the user to run any command as the root user
+
+~~~ bash
+sudo shutdown -r now
+~~~
+
+The above command shuts down the system as the root user
+
+---
+
+### Useful Options / Examples
+
+#### `sudo -u`
+
+The `-u` (user) option causes `sudo` to run the specified command as a user other than root
+
+##### Example
+
+`sudo -u c4cs ls /home/Document`
+
+This command lists the contents of `/home/Documents` as the user c4cs
+
+#### `sudo -v`
+
+The `-v` (validate) option updates the users timestamp and extends the `sudo` timeout for 5 minutes
+
+Assuming one already has sudo access, running this command will allowing them to continue using the same sudo privledges for 5 minutes without authentication
+
+#### `sudo -k`
+
+The `-k` (kill) option removes a user's timestamp from `sudo` and takes away their root privledges
+
+The next sudo command will require a password
+
+### `sudo -b`
+
+The `-b` (background) option will run the command listed in `sudo` in the background
+
+#### Example
+
+`sudo -b g++ hugeFile0.cpp hugeFile1.cpp hugeFile2.cpp -o largeExecutable`
+
+This command will compile the three given files (potentially taking a very long time) in the background as the root user
