Execute

The module provides convenient way to execute external commands and deal with its stdout/stderr as well as with stdin (see unit tests for examples)

command := MakeCommand("sed", "-e", "s/a/A/g")
execution, _ := Execute(command)

execution.Stdin <- []byte("aaa")
close(execution.Stdin)

for run := true; run; {
    select {
    case out := <-execution.Stdout:
        fmt.Print(string(out))
    case err := <-execution.Stderr:
        fmt.Println(string(err))
    case <-execution.Exit:
        run = false
    case <-time.After(time.Second * 3):
        t.Error("process killed by timeout")
        execution.Kill()
        run = false
    }
}
