Let's think about it this way for a moment
Because Raspberry Pi OS is a Debian-based Linux distro, everything from the Linux tutorial — commands and concepts like the filesystem hierarchy, permissions, and package management — applies directly on the Raspberry Pi too. You can think of the Raspberry Pi as 'a physical device for practicing Linux.' You can open the Terminal application from the taskbar in desktop mode, or in headless mode, you land straight in a terminal via SSH.
Let's connect this to a real-world scenario
When creating project folders and managing files in your Raspberry Pi's home folder (/home/pi, or whatever username you set up), you can directly reuse the Linux tutorial's 'Files & Filesystem' chapter (pwd, ls, cd, mkdir, cp, mv) — even plugging in a USB drive formatted as vfat and having it auto-mount under /media follows exactly the filesystem hierarchy concept from the Linux tutorial.
Let's look at an example together
pwd
ls -la
mkdir my-first-project
cd my-first-project
touch notes.txt
cat /etc/os-release # Raspberry Pi OS version စစ်Running cat /etc/os-release shows 'Raspberry Pi OS' (Debian-based) information in the terminal.5-Minute Try-It
On a Raspberry Pi (if you have one) or your Linux tutorial VM/WSL, create a new project folder, run cat /etc/os-release, and read through the OS information.
A quick word of caution
A Raspberry Pi's SD card storage is limited (much smaller than a laptop hard drive), so you should check disk space regularly using the Linux tutorial's 'Disk & Storage' lesson (df -h, du -sh).
