如何通过python执行Shell脚本 [英] How to execute a shell script through python

问题描述

我有一个脚本，例如abc.sh，其中包含带有标志的命令列表. 例子

I have a script say abc.sh which has list of commands with flags. example

//abc.sh
echo $FLAG_name
cp   $FLAG_file1   $FLAG_file2
echo 'file copied'

我想通过python代码执行此脚本. 说

I want to execute this script through python code. say

//xyz.py

name = 'FUnCOder'
filename1  = 'aaa.txt'
filename2 = 'bbb.txt'

subprocess.call([abc.sh, name, filename1, filname2], stdout=PIPE, stderr=PIPE, shell=True)

此呼叫无法正常工作.

还有哪些其他选择?

shell脚本文件也位于其他目录中.我希望输出记录在日志中.

Also the shell script file is in some other directory. And I want the output to go in logs.

推荐答案

通常，您要使用 Popen ，因为您之后具有流程控制权.试试:

Usually you want to use Popen since you have process control afterwards. Try:

process = subprocess.Popen(['abc.sh', name, filename1, filname2], stdout=PIPE, stderr=PIPE)
process.wait() # Wait for process to complete.

# iterate on the stdout line by line
for line in process.stdout.readlines():
    print(line)
