确定是否从Python中的脚本调用程序 [英] Determine if the program is called from a script in Python

问题描述

doa

#!/bin/sh
myexe

myexe

if sys.stdout.isatty():
    print 'from a script'
else:
    print 'not from a script'

输出(如果我从终端执行doa):

OUTPUT (if i execute doa from terminal):

not from a script

输出(如果我从终端执行myexe):

OUTPUT (if i execute myexe from terminal):

not from a script

如果要从doa执行，我希望它说'from a script'

I want it to say 'from a script' if executed from doa

问题:myexe是否有可能知道它是从bash脚本执行的?

Question: is it possible for myexe to know that it's being executed from a bash script?

推荐答案

您可以使用psutil询问ID为父进程ID的进程的名称:

You can use psutil to ask for the name of the process with id the parent process id:

import psutil
import os

ppid = os.getppid() # Get parent process id
psutil.Process(ppid).name() == "bash"

您可以使用pip命令安装psutil:

pip install psutil
