RT-11 was an OS for the PDP-11. Overall it has a very OS/8 feel to it.

The filesystem was like that of OS/8 in that files are stored complete on the disk, so that if you delete them the disk will need to be 'squished' back down. http://www.vaxdungeon.com/

Commands
These are a few commands that I've managed to work out, in no particular order.
DIR command
Just like MS-DOS
RUN command
Dungeon for example is executed with RUN. I think you have to run .sav files.
@ command
COM files are like batch scripts, and are executed with the @ infront of them.
Squish command
Disks will need to be 'defraged' or compacted with this command. In some version it'll just be SQU.
.SQU Device? DK0: RK0:/Squeeze; Are you sure? Y
SHOW command
This is a very usefull command to show some info about the OS.
.SHOW
