mkdir: Create Directories

You can move around the station. Now it is time to build. The first building block is a new directory (folder).

The mkdir command (make directory) creates a folder. Give it the name you want:

mkdir reports

Nothing is printed when it succeeds: Linux stays quiet on success. Run ls to confirm the folder appeared:

ls

reports

Making several folders at once

mkdir accepts more than one name:

mkdir logs data backups

That creates three folders in one go.

Nested folders: mkdir -p

What if you want a folder inside a folder that does not exist yet? This fails:

mkdir projects/website

mkdir: cannot create directory 'projects/website': No such file or directory

The -p option (parents) tells mkdir to create every missing folder along the path:

mkdir -p projects/website

Now both projects and projects/website exist.

Mission: Build a Workspace

The station needs a new directory structure for the upcoming mission. You will set it up from scratch.

1. Create a folder called mission.
2. Inside it, create three sibling folders in a single command: mission/logs, mission/data and mission/backups.
3. In one command, create the nested path mission/logs/day1 at once, including any parent folders that don't exist yet.
4. Verify the whole structure as a tree.

Expected result

The tree of mission shows logs, data and backups, with day1 nested inside logs.
