Functions

func ListCmds

func ListCmds()

ListCmds lists bb commands and verifies symlinks. It is by convention called when the bb command is invoked directly. For every command, there should be a symlink in /bbin, and for every symlink, there should be a command. Occasionally, we have bugs that result in one of these being false. Just running bb is an easy way to tell if something in your image is messed up.

func Register

func Register(name string, init, main func())

Register registers an init and main function for name.

func RegisterDefault

func RegisterDefault(init, main func())

RegisterDefault registers a default init and main function.

func Run

func Run(name string) error

Run runs the command with the given name.

If the command's main exits without calling os.Exit, Run will exit with exit code 0.
