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

# Overview

Let’s look at how we can run multiline commands on the shell. As soon as we press the “Enter” key, the shell executes the command. However, some commands have many options or are just very long and might not fit on our screen, and we’d like to break the command into multiple lines. We can do this by typing the `\` character before pressing “Enter.”


In [Creating Pipelines of Data](https://www.educative.io/courses/harnessing-power-command-line-interface/creating-pipelines-of-data), we saw this example, which lets us see the most used commands in our history:



```bash
$ history | awk '{c[$2]++}END{for(i in c){print c[i] " " i}}' | sort -rn | head
```

# Breaking the command

We can break this command onto multiple lines by using the `\` character, like this:

```bash
history \
| awk '{c[$2]++}END{for(i in c){print c[i] " " i}}' \
| sort -rn \
| head
```
Use the terminal below to practice these commands.
