The default size buf was used to read the command execution result, resulting in an incomplete command execution result.

[Li4n0]

func (ssh_conf *MakeConfig) Stream(command string, timeout ...time.Duration) (<-chan string, <-chan string, <-chan bool, <-chan error, error) {
	... ...
	// combine outputs, create a line-by-line scanner
	stdoutReader := io.MultiReader(outReader)
	stderrReader := io.MultiReader(errReader)
	stdoutScanner := bufio.NewScanner(stdoutReader)
	stderrScanner := bufio.NewScanner(stderrReader)
	... ...

The default buf size is 4096. This results in an incomplete output when the command stdout or stderr is greater than this value

So will this problem be solved? @appleboy

[fatelei]
