Function CombinedOutputLines

pkg/image/exec/exec.go:66–76

CombinedOutputLines is like os/exec's cmd.CombinedOutput(), but over our Cmd interface, and instead of returning the byte buffer of stderr + stdout, it scans these for lines and returns a slice of output lines

(cmd Cmd)

// but over our Cmd interface, and instead of returning the byte buffer of
// stderr + stdout, it scans these for lines and returns a slice of output lines
func CombinedOutputLines(cmd Cmd) (lines []string, err error) {
	var buff bytes.Buffer
	cmd.SetStdout(&buff)
	cmd.SetStderr(&buff)
	err = cmd.Run()
	scanner := bufio.NewScanner(&buff)
	for scanner.Scan() {
		lines = append(lines, scanner.Text())
	}
	return lines, err
}

// InheritOutput sets cmd's output to write to the current process's stdout and stderr
func InheritOutput(cmd Cmd) {
