Before answering the questions below, you should know that exec.Command will not do shell glob expansion since it does not invoke commands via a shell. If you want to do that you can either invoke via a shell or do the globbing yourself with filepath.Glob[1].
1. You can capture the combined output or stderr using the exec.Cmd CombinedOutput method or Stderr field respectively. 2. exec.Command does not know anything about recursive copy of directories, it just invokes commands. 3. This depends on exactly what it is that you are trying to achieve.
