var Cmd = &command.Command{

		Use:   "bash",
		Short: "Generates shell autocompletion file for Triton",
		Long: `Generates a shell autocompletion script for Triton.

By default, the file is written directly to /etc/bash_completion.d
for convenience, and the command may need superuser rights, e.g.:

	$ sudo triton shell autocomplete bash

Add ` + "`--bash-autocomplete-dir=/path/to/file`" + ` flag to set alternative
folder location.

Logout and in again to reload the completion scripts,
or just source them in directly:

	$ . /etc/bash_completion`,
