I have a shell script named test.sh. How can I trigger the test.sh from Ruby?
我有一个名为test.sh的shell脚本。如何从Ruby触发test.sh？
I want test.sh to run as a background process, what means in Ruby it is a ansync call.
我希望test.sh作为后台进程运行，这意味着在Ruby中它是一个ansync调用。
STDERR and STDOUT also need to be written to a specific file.
还需要将STDERR和STDOUT写入特定文件。
Any ideas?

@TanzeebKhalili's answer works, but you might consider Kernel.spawn(), which doesn't wait for the process to return:
@ TanzeebKhalili的答案有效，但您可能会考虑Kernel.spawn（），它不会等待进程返回：
pid = spawn("./test.sh")
Process.detach(pid)
Note that, according to the documentation, whether you use spawn() or manually fork() and system(), you should grab the PID and either Process.detach() or Process.wait() before exiting.
请注意，根据文档，无论是使用spawn（）还是手动fork（）和system（），都应该在退出之前获取PID和Process.detach（）或Process.wait（）。
Regarding redirecting standard error and output, that's easy with spawn():
关于重定向标准错误和输出，使用spawn（）很容易：
pid = spawn("./test.sh", :out => "test.out", :err => "test.err")
Process.detach(pid)

Try this:
尝试这个：
Process.fork { system "./test.sh" }
Won't work on windows, for which you can use threading.
