I tried

C:\>DOSKEY /listsize=0

That seems to remove the history in cmd.exe?

Hi,

I have tried irb after this command:

> C:\>DOSKEY /listsize=0

That bug is still there. But when I use the old [command.com](http://command.com) it’s all

Yes, it does - thanks.

Unfortunately, irb’s readline still doesn’t work, so my theory was  
wrong. Oh well.
