A Unix-like operating system simulator written in Python. PyOS provides a shell environment (bash-like) with file system and user management with Unix-style commands.

• File system simulation: with directory structure within a virtual file system.
• System setup: installation process, machine name setting, root password setting, user creation.
• Package manager: with remote package installation.
• Python: support with virtual environment (venv).
• Permission and authentification system: owner-based access control and multi-user support

PyOS provides 36 commands in total: 34 are installed by default during system setup, and 2 additional commands (nano and neofetch) can be installed via the package manager:

* These commands (nano and neofetch) are not pre-installed. They must be installed via the package manager (snakepkg) first.

• Python: 3.6 or higher
• Dependencies: Install via requirements.txt
• Internet connection: internet connection for package manager features
