	Use:   "genautocomplete",
	Short: "Generate shell autocompletion script for Hugo",
	Long: `Generates a shell autocompletion script for Hugo.

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) {
		if autocompleteType != "bash" {
			jww.FATAL.Fatalln("Only Bash is supported for now")
		}
		err := cmd.Root().GenBashCompletionFile(autocompleteTarget)
		if err != nil {
			jww.FATAL.Fatalln("Failed to generate shell completion file:", err)
		} else {
			jww.FEEDBACK.Println("Bash completion file for Hugo saved to", autocompleteTarget)
		}
	},
