Headless Mode

Back to Interactive Shell

Tips

• Use run --push-status myfunc to avoid clobbering $?.
  • Note that run also runs the function with errexit on, which is probably what you want.
  • TODO: should be provide a way to load a function ahead of time? Like --rcfile but doesn't replace the user's oshrc ?
