When you use a default Terminal + Bash from Ubuntu 20.02.1 LTS with Gnome 3.36.3, ps aux seems to automatically include the unlimited width.

But when I use powershell or xterm, the ps aux is truncated by default, and you have to manually specify auxww to get the full output.

Which makes me think that this is controlled by some sort of environment variable.

What makes ps aux automatically default to ww so that the output is not truncated? In my case, I never want the ps aux output to be truncated.
