子进程等待等待脚本完成

Question

我正在调用子进程(期望脚本运行一些命令)，并且需要等待直到它完成启动另一个函数，但是我认为它只等待直到shell命令完成，而不是期望脚本。可以等整个流程完成吗?

 p111 = subprocess.Popen('gnome-terminal -e "perl /tmp/expect',shell=True)  
    os.waitpid(p111.pid,0)
    smo_final()

Answer 1

使用

https://docs.python.org/2/library/subprocess.html subprocess.Popen.wait

  p11 = subprocess.Popen('gnome-terminal -e "perl /tmp/expect',shell=False)  
  p11.wait()

Answer 2

使用python期望实现pexpect

import pexpect
...
child = pexpect.spawn(cmd) # the command you want to run
child.expect(str_expect) # the string you expect 
child.sendline(str_response) # the string with which you'd like to respond 
child.wait() # wait for the child to exit
...
# the rest of your code here
