RustOS is a small, custom operating system built in Rust. It is designed as an educational project and includes core components commonly found in operating systems.
- Interrupt handling
- File system
- Terminal interface
- Task scheduling
- Input/Output (I/O) operations
- Memory management
- Heap allocation
The system runs in a single terminal screen with no graphical interface.
Upon boot, the system displays the OS logo and opens a command-line terminal where users can interact using a keyboard.
shutdown: Shut down the machinereboot: Restart the machineecho: Print the entered textclear: Clear the terminal screenhelp: Display a list of available commandslogo: Clear the screen and show the system logocat: Display file contentswrite: Overwrite content of an existing fileappend: Add content to the end of a filels: List contents of the current directorytouch: Create a new filemkdir: Create a new directoryrm: Delete a file or directorycd: Change the current directory
After each command, background operations like disk access or output are performed.
If there is no red error message, the operation succeeded.
Note: File and directory operations will fail with an error message if the target does not exist—no automatic creation is performed.
