screen/byobu presence inferred by an environment variable

Asked by Jan Dahl

Hey there,

I've recently discovered that $STY is set when running a terminal in byobu (or screen). I think i would be suitable to add to the documentation (https://help.ubuntu.com/10.04/serverguide/byobu.html).

Proposed addition:

You can check for the presence of byobu in your scripts by checking for the $STY environment variable, e.g.

<pre>if [ -n $STY ]; then...</pre>
