打开两个自己的终端，运行两个脚本并等待它们完成

Question

I have a script which amongst others, gives the option to run an process . I'm not talking about one executable, but about two python scripts which need to be run in an own terminal and produce output in the terminal.

I've considered script1 = subprocess.call(["/dir/python","/dir/script1","param"]) , or the same with /bin/bash but this seems to run the python/bash the in the current terminal - not as an own window.

If I'd do script1 = subprocess.call(["/usr/bin/xterm","param to run bash and my script"]) , a new window opens, but then the described problem below applies.

The other conceptual problem I have is, that I need to wait for both scripts. So if calling the subprocess would work, it'd wait when the first is called until it's done, then start the second, but they need to run simultaneously.

How do I start two new terminals, each starting a specified script?

Answer 1

To run commands and wait for them to finish you run them in the background and then use the shell wait built-in to tell the shell to wait for background jobs to finish.
