Chapter 3: Command Line Basics

Set your working directory to the root directory.
```
$ cd /
```
Set your working directory to your home directory using three different commands.
- Method 1:
```
$ cd
```
- Method 2:
```
$ cd ~
```
- Method 3: Absolute Path
```
$ cd /path/to/your/home/directory
```
Find a folder on your computer using your file and folder browser, and then set your working directory to that folder using the terminal.
```
$ cd path/to/the/folder
```
List all of the files and folders in the directory you navigated to in #3.
```
$ ls folder
```

Create a new directory called workbench in your home directory.
```
$ cd

$ mkdir workbench
```
Without changing directories create a file called readme.txt inside of workbench.
```
$ touch workbench/readme.txt
```

Append the numbers 1, 2, and 3 to readme.txt so that each number appears on it’s own line.

$ echo 1 > workbench/readme.txt

$ echo 2 >> workbench/readme.txt

$ echo 3 >> workbench/readme.txt

Print readme.txt to the command line.
```
$ cat workbench/readme.txt
```
Use output redirection to create a new file in the workbench directory called list.txt which lists the files and folders in your home directory.
```
$ ls > workbench/list.txt
```
Find out how many characters are in list.txt without opening the file or printing it to the command line.
```
$ wc -c workbench/list.txt
```

Copy the message.txt you just moved into your home directory.

$ cd

$ cp path/to/another/directory/message.txt message.txt
