Plan9 is an operating
system by the authors of the original Unix, with integrated
support for distributed applications.
Plan9 has its own windowing system,
rio, quite different from
It is possible to connect to Plan9 machines
from Unix machines running X11.
starts the windowing system on the remote Plan9 and
everything works as if sitting in front of it.
While typing from one machine I remembered I had
already solved a problem in a one-liner,
but on a different drawterm which ran on a Unix box miles away.
cpu% echo $wsys
cpu% lc /srv/rio.*
So the other drawterm runs the
rio mounted on
/srv/rio.myname.5678. To get at the scrollback
of a window displayed on a screen on a totally different machine:
cpu% mount /srv/rio.myname.5678 /n/wsys 1
cpu% cat /n/wsys/text
[...lines of output...]
[...including the one-liner...]
