	NOTE: The current version supports Bash only. This should work for *nix systems with Bash installed.
	
	By default the file is written directly to /etc/bash_completion.d for convenience and the command may need superuser rights, e.g:
	
	sudo hugo genautocomplete
	
	Add --completionfile=/path/to/file flag to set alternative file-path and name.
	
	Logout and in again to reload the completion scripts or just source them in directly:
	
	. /etc/bash_completion
	`,
	Run: func(cmd *cobra.Command, args []string) {
