You can practice the taught commands on the command line at the bottom of the page. Execute the given tasks on the same command line.

Next, we will practice working with directories. Let's start by creating a new directory using the 

command. The command comes from the words 

, which literally means create a directory.

In the image below, we created a new directory named "harjoitus" and ensured that it was successfully created using the ls command.

It is also possible to create multiple directories by giving them consecutively to the 

In the image below, we created two new directories and verified that they were created successfully.

It is also possible to create new directories nested by giving the 

In the image below, we created two nested directories and confirmed the successful execution of the command by running the ls command from inside the first directory.

Task 1

Task 2

Create the directory structure ~/projects/linux/2023

Task 3

Use the mkdir command in the desired way and build the directory structure according to the instructions.

In a Linux environment, the tilde (~) character refers to the user's home directory, meaning that ~/ is the same as /home/student/. The directory ~/example is the same as the directory /home/student/example.

Next, we will practice working with directories. Let's start by creating a new directory using the *mkdir-*command. The command comes from the words *make directory*, which literally means create a directory.

```sh
mkdir directory
```

It is also possible to create multiple directories by giving them consecutively to the *mkdir* command.

```sh
mkdir direcotry1 direcotry2 directory3
```

*In the image below, we created two new directories and verified that they were created successfully.*

It is also possible to create new directories nested by giving the *mkdir-* command the *-p -* switch.

```sh
mkdir -p directory1/directory2/directory3
```

*In the image below, we created two nested directories and confirmed the successful execution of the command by running the ls command from inside the first directory.*

Creating directories

Start here. In this course, we go through important basics that enable in-depth learning of increasingly complex topics in information security. The course is intended for students who are new to information technology.

The purpose of the course is to go through important topics in information technology so that it would be easier to internalize new information in other courses. The purpose of the course is to support learning and enable a quick transition to other material offered by Hakateam. We have done our best to condense the course into what we believe are the most critical areas, but we still recommend seeking additional information and trying out new things in the field of information technology. Continuous learning is a part of every enthusiast's as well as IT professional's life.
