Title Body

I need to find a way to read a line from a io.ReadCloser object OR find a way to split a byte array on a "end line" symbol. However I don't know the end line symbol and I can't find it. My application execs a php script and needs to get the live output from the script and do "something" with it when it gets it. Here's a small piece of my code: cmd := exec.Command(prog, args) /* cmd := exec.Command("ls")*/ out, err := cmd.StdoutPipe() if err != nil { fmt.Println(err) } err = cmd.Start() if err != nil { fmt.Println(err) } after this I monitor the out buffer in a go routine. I've tried 2 ways. 1) nr, er := out.Read(buf) where buf is a byte array. the problem here is that I need to brake the array for each new line 2) my second option is to create a new bufio.reader r := bufio.NewReader(out) line,_,e := r.ReadLine() it runs fine if I exec a command like ls , I get the output line by line, but if I exec a php script it immediately get an End Of File error and exits(I'm guessing that's because of the delayed output from php) EDIT: My problem was I was creating the bufio.Reader inside the go routine whereas if I do it right after the StdoutPipe() like minikomi suggested, it works fine
