Show HN: A DOS-like hobby OS written in Rust and x86 assembly

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

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.

https://en.m.wikipedia.org/wiki/86-DOS

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.

`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).

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.

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.

Love it.

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?`.

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

CAT was on the Amstrad CPC.
