In short, Webinoly is developed and documented using Bash and some kind of commands will not work as expected if entered in a different shell, sudo site example.com -proxy=[localhost:8082], for instance. It will fail in ZSH.
You should note that “interactive shell”, is not the same as “login shell”.
As you can see, a lot of examples shown in our documentation will not work. and users can be easily get confused. For advanced users we have an option to disable this shell check, in Webinoly configuration file set: shell-check:false.
