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

notes
The file system is like that of OS/8 in that files are stored contiguously on the disk. If a new file does not fit in a 'hole' left by an old deleted file, the files on the disk must be moved together to create a larger area of free space. http://www.vaxdungeon.com/

Commands
These are a few commands that I've managed to work out, in no particular order.
COPY command
The copy command is a little weird in how wildcards work.
copy dx0:*.* *.*
Is the best way to copy the disk files into the working disk.....
DIR command
Just like MS-DOS

type command
The type command will show the contents of a file, just like MS-DOS.
.TYPE STARTS.COM D 56=5015 TYPE V4USER.TXT D 56=0
RUN command
Dungeon for example is executed with RUN. I think you have to run .sav files.
.RUN DUNGEO Welcome to Dungeon. This version created 10-AUG-78. You are in an open field west of a big white house with a boarded front door. There is a small mailbox here. >
@ command
COM files are like batch scripts, and are executed with the @ infront of them.
.@STARTS.COM .D 56=5015 .TYPE V4USER.TXT Welcome to RT-11 Version 4. RT-11 V04 provides new hardware support and some major enhancements over Version 3B. Please use the HELP command; it describes the new options in many of the utilities. If you are using a terminal that requires fill characters, modify location 56 with a Deposit command before proceeding with system installation. LA36 DECwriter II and VT52 DECscope terminals do NOT require such modification.
SQUEEZE 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

RK0 = SY , DK
