var Cmd = &command.Command{
	Name: cmdName,

	Cobra: &cobra.Command{
		Use:   cmdName,
		Short: "Generates and install " + buildtime.PROGNAME + " bash autocompletion script",
		Long: `Generates a bash autocompletion script for ` + buildtime.PROGNAME + `

By default, the file is written directly to ` + config.DefaultBashAutoCompletionDir + `
for convenience, and the command may need superuser rights, e.g.:

	$ sudo vpc shell autocomplete bash

Add ` + "`--bash-autocomplete-dir=/path/to/file`" + `. The default file name
is ` + buildtime.PROGNAME + `.sh.

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

	$ . /bash_completion.d`,
