Types

type ExecCmd

type ExecCmd struct {
	Cmd *exec.Cmd
}

implementation of IExecCmd with os.Process embed

func NewExecCmd

func NewExecCmd(command *exec.Cmd) *ExecCmd

NewExecCmd returns a new instance of the ExecCmd

func (*ExecCmd) Kill

func (p *ExecCmd) Kill() error

Kill causes the Process to exit immediately. Kill does not wait until the Process has actually exited. This only kills the Process itself, not any other processes it may have started.

func (*ExecCmd) Pid

func (p *ExecCmd) Pid() int

Pid returns the process id.

func (*ExecCmd) Signal

func (p *ExecCmd) Signal(sig os.Signal) error

Signal sends a signal to the command process

func (*ExecCmd) Start

func (p *ExecCmd) Start() error

Start starts the command execution process with the Cmd.

func (*ExecCmd) Wait

func (p *ExecCmd) Wait() error

Wait releases any resources associated with the Cmd.

type IExecCmd

type IExecCmd interface {
	Pid() int
	//kill the attached child process
	Kill() error
	//start the command execution process
	Start() error
	//wait for the child to finish
	Wait() error
	// sends a signal to the command process
	Signal(sig os.Signal) error
}

IExecCmd is an abstracted interface of os.Process
