Types

type Cmd

type Cmd struct {
	// Command is the command to run remotely. This is executed as if
	// it were a shell command, so you are expected to do any shell escaping
	// necessary.
	Command string

	// Stdin specifies the process's standard input. If Stdin is
	// nil, the process reads from an empty bytes.Buffer.
	Stdin io.Reader

	// Stdout and Stderr represent the process's standard output and
	// error.
	//
	// If either is nil, it will be set to ioutil.Discard.
	Stdout io.Writer
	Stderr io.Writer

	// This thing is a mutex, lock when making modifications concurrently
	sync.Mutex
	// contains filtered or unexported fields
}

Cmd represents a remote command being prepared or run.

func (*Cmd) Err

func (c *Cmd) Err() error

Err returns any communicator related error.

func (*Cmd) ExitStatus

func (c *Cmd) ExitStatus() int

ExitStatus returns the exit status of the remote command

func (*Cmd) Init

func (c *Cmd) Init()

Init must be called by the Communicator before executing the command.

func (*Cmd) SetExitStatus

func (c *Cmd) SetExitStatus(status int, err error)

SetExitStatus stores the exit status of the remote command as well as any communicator related error. SetExitStatus then unblocks any pending calls to Wait. This should only be called by communicators executing the remote.Cmd.

func (*Cmd) Wait

func (c *Cmd) Wait()

Wait waits for the remote command to complete.
