No, at least not by default (https://pkg.go.dev/bufio#Scanner.Buffer). But that that point you want to start questioning why you're doing what you're doing. Your invocation of grep can be a lot simpler ``` func grep(match string, r io.Reader, stdout, stderr io.Writer) error { cmd := exec.Command("fgrep", match) cmd.Stdin = r cmd.Stdout = stdout cmd.Stderr = stderr return cmd.Run() } ``` You can then do whatever you want with the buffered output and stderr. You can also make this use a pipe with minor changes if you expect the output to be long and that stream processing of that would be sensible (use cmd.Start instead of Run and look into StdoutPipe). -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
