Similarly to how we piped the script into our shell covered in local usage, we can also use this in GitHub Actions, like so: -name:Wait for the database to startrun:wget -qO- https://raw.githubusercontent.com/eficode/wait-for/$WAIT_FOR_VERSION/wait-for | sh -s -- localhost:5132...

p = subprocess.Popen("calc",shell=True) for i in range(10) : print (i) 1. 2. 3. 4. 5. Popen.wait() Popen.wait()函数使得父进程等待新创建的进程运行结束,然后再继续父进程的其他任务。且此时可以在Popen.returncode中得到新进程的返回值。
