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

What a challenge! Need to implement some interrupts it seems then, to provide an API for filesystem and so... Thank you for such idea

Doomgeneric has a very thin platform-specific layer: https://github.com/ozkl/doomgeneric?tab=readme-ov-file#porti...

I want some TSRs and print spoolers...

DOOM required DOS 5.0. rou2exOS is only the second take. Watch this area ;)

Borland languages and xBase ecosystem as well

Nobody cares about Lotus 1-2-3 support any longer :)

What about Wordstar?

The text editor JOE has a WordStar mode.

WordPerfect was better anyway :) (SCNR)

also, can't be a dos with the 'dir' command.

Afaik there is a 'DIR' command in MS-DOS. Anyway, what would be a better command to list a directory? I could think of 'ls' maybe

I would most likely end up with something like this:

  CAT          CATalogue - output the contents of current directory
  RM           to Raster Memory - load contents of named file in framebuffer
  MV           Make Virtual - map the file into memory and output the address
  LS           Load System - attempt to reboot using the named file as the kernel
  CD           Create Directory - self-explanatory
  SH           System Halt - immediately stop all processing

...and so on.

I suggest:

    RM           Relocate me - you could also use the "-rf" flag to relative fuzzy matching, for instance `rm -rf tmp` to find any temp-like folder near your current location. Pretty standard stuff.
    CD           Clear data - `cd -L /temp` would "liquidate" the directory.

This would be a much simpler command interface.

To create a file, we should take inspiration from TOPS-10 and call the command `make` [0]. When issuing `make love`, it should ask for confirmation to the user: `not war?`.

Very good design. Implements only the essential tasks an operator would need with concise and well-known mnemonics. I’m sure this will be immediately intuitive to anyone, with no potential for mistakes whatsoever.

CAT was on the Amstrad CPC.

Love it.

As someone old enough to have started on MS-DOS 3.3, dir has been there all time.

CATALOG, DSPFLR, Get-ChildItem

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).
