In `bash` you am able to export a variable to prevent `/etc/hosts` from being used with autocompletion of the `ssh` command:
export COMP_KNOWN_HOSTS_WITH_HOSTFILE=””
You can try that setting that in `zsh` but it won’t work. If you’ve tried searching in the `zsh-completions` directory but couldn’t find anything similar, it’s because it’s not there.
So, how can you prevent `zsh` from autocompleting ssh hosts with the `/etc/hosts` file?
Add this to your `~/.zshrc` file:
zstyle ‘:completion:*’ hosts off
