When you start the ROOT interpreter of run a script from the terminal, you just run:
> root --web=off
instead of:
> root
If you don’t want to do this every time, you can also add this line to the .rootrc
file in your home directory:
Browser.Name: TRootBrowser
If the ~/.rootrc
file doesn’t exist yet, you need to create it manually.
