Shell脚本从python程序获取输入 [英] shell script taking input from python program

问题描述

我有一个运行脚本的shell脚本，该程序具有自己的参数:

I have a shell script which runs a python program which has its own parameters:

#!/bin/bash
python blah.py var1 var2
./run key

我需要找到一种从python程序中检索密钥内容的方法.我试过只是让python程序返回值，然后做:

I need to find a way to retrieve the contents of key from the python program. I have tried just making the python program return the value, and then doing :

key=python blah.py var1 var2

在我的shell脚本中，但这没有用，因为它指出密钥在函数外部".

in my shell script, but that didn't work because it stated key was "outside the function".

预先感谢

推荐答案

使用此

key=`python blah.py var1 var2`
./run $key
