Plan 9
Plan9 is a UNIX inspired non-commercial graphical research OS. It has a lot of interesting ideas, pushing the “everything is a file” philosophy to the limit. It is very different from UNIX and can take some time getting used to it.
System update
To update the system, webfs must be running, since we
need to sync the mercurial repository. This is probably one of the first
things you want to do after a fresh install.

cd /sys/src
mk clean
mk installRio
Rio is the window-manager of Plan 9. It has a lot of nice ideas and
relies on a 3 button mouse for all operations. Left click
(mouse 1) is used to select text and put the cursor on the
desired location. Right click (mouse 3) will open Rio menu
if used on the desktop or terminal, which allow us to create new
windows, resize, move, delete or hide them. Middle click will open the
terminal options such as copy and paste.
Combining mouse presses (also known as “chording”) can be used to
different effects. For example selecting text with mouse 1
and without releasing it, pressing the middle button
(mouse 2) will cut the text. If we then hold
mouse 1 and press mouse 3 the contents will be
pasted. To copy text (snarf) instead of cutting it, just
follow the cut with a paste before releasing mouse 1, so
(hold) mouse 1 -> (press) mouse 2 -> (press) mouse 3.
For scrollable windows, using the scroll wheel works as expected.
Pressing mouse 1 or mouse 3 directly on the
scroll bar will scroll up or down respectively. Pressing and holding
mouse 2 allow us to drag scroll.
Graphical programs will replace the terminal when run and may
interact differently with mouse usage. For example in acme
middle click on some text will attempt to execute it
(e.g. mouse 2 on Newcol text will create a new
column and highlighting ls $home and pressing
mouse 2 on it will execute the command as if ran on the
terminal and paste the output on a new buffer).
To customize the look and feel of Rio and add a wallpaper if desired see this.
