Types

type Cmd

type Cmd struct {
	*exec.Cmd
}

func Command

func Command(name string) (*Cmd, error)

Command returns the Cmd struct to execute the command. No need to split the path and arguments. The error may be caused by unclosed quote.

func (*Cmd) StderrChannel

func (c *Cmd) StderrChannel() (chan string, error)

StderrChannel returns a channel that will be connected to the command's standard error when the command starts. It closes when StderrPipe closed.

func (*Cmd) StdinChannel

func (c *Cmd) StdinChannel() (chan string, error)

StdinChannel returns a channel that will be connected to the command's standard error when the command starts.

func (*Cmd) StdoutChannel

func (c *Cmd) StdoutChannel() (chan string, error)

StdoutChannel returns a channel that will be connected to the command's standard error when the command starts. It closes when StdoutPipe closed.
