In this course, you will get the chance to explore the command-line interface (CLI), starting with basics like navigating file systems and working with directories and files. Then, you will use those building blocks to tackle more advanced features and tasks within the CLI. You will also learn to turn basic commands into executable scripts and easily automate common tasks. This course will empower you to put the interface to work, take complete control of your computer, and hack your way to productivity.

Harnessing the Power of the Command-Line Interface

## The `sort` command

The `sort` command can sort output alphabetically or numerically. Not every program sorts its output, but we can pipe the output to sort when needed.

Remember the `words.txt` file we created earlier? Let’s use `sort` to sort the lines of the file alphabetically:

```
$ sort words.txt
```
Run the complete code on the terminal below for practice.
```bash
cat << 'EOF' > words.txt 
blue
apple
candy
hand
fork
EOF
sort words.txt
```

We can use the `-r` switch to sort the file in reverse with the following code: `sort -r words.txt`.

We can use the `-R` flag to sort the lines randomly with the following code: `sort -R words.txt`.

Like with other programs, we can use `sort` in a pipeline, which means we can use it to sort the output of another command.

> The same switches apply to numeric inputs.

Use the terminal below for practice.
