To try it out, simply build the project yourself from source, or use attached bootable ISO image of the system (in Releases on Github) and run it in QEMU.

Memory-safe language. x86_64, with Arm on the roadmap. Networking stack. Boots from a CD and via multiboot. Your hobby project wipes the floor with DOS.

Whoa there. Gotta run Doom and BASIC to compete with DOS. That is the officially recognized DOS-Kármán line.

It would seem to logically follow that a Disk Operating System would have a directory list utility for disks like ‘dir’. It was there in the first version called 86 DOS.

`dir` was also in CP/M. Though it didn't have a concept of a file hierarchy, so it listed all files on the disk (but did support supplying a pattern to filter against).
