Types

type Cmder

type Cmder struct{}

Cmder handles running subprograms synchronously and asynchronously.

func New

func New() *Cmder

func (*Cmder) Run

func (c *Cmder) Run(cmd *exec.Cmd) (output string, err error)

Run runs a command in a blocking manner, returning its output and an error if it failed.

func (*Cmder) Start

func (c *Cmder) Start(cmd *exec.Cmd) (
	stdoutLines, stderrLines <-chan string,
	waitError <-chan error, startErr error)

Start launches a command and streams stdout and stderr to channels. All the channels returned are ready only and won't be closed if the command fails later.
