2 years ago I'd really rather leave handling non-default behavior to the user. By default, zsh clobbers and rm runs without -i and this is the expected behavior. For example if someone decides to alias rm in /etc/zshenv or /etc/zsh/zshenv then invoking zsh with -f won't help anyway, which is why figuring out non-default behavior is out-of-scope for this script. The user should handle any non-default configuration they may have set.
In case the user has some zsh RC files (e.g. .zshrc), it should be better to ignore them when running macos-guest-virtualbox.sh, by adding -f option to zsh's command line. Otherwise, the script might not run smoothly (e.g. rm might ask for confirmation of every single file deletion if it was aliases to "rm -i" in .zshrc), or even break (if the noclobber option of zsh was set up in .zshrc). As an additional caution, the option noclobber can be deactivated in the beginning of the script --- that way, lines overwriting or adding to .sh or .txt files will still work even though .zshrc was read and set this option.
