将参数传递给 subprocess.Popen

[英]Passing args to subprocess.Popen

Prinz 2023-01-31 03:32:34 20 1 python/ subprocess

需要调用grep from python grep 命令： grep -B 5 -A 5 "make.*Error|Error-" file

尝试了 escaping 的各种组合，正则表达式使其与 subprocess.Popen 一起使用

proc = subprocess.Popen(['grep','-B 5', '-A 5', r'"make.*Error|Error-"', file], stdout=subprocess.PIPE, stderr=subprocess.PIPE)

我是否缺少某种转义字符以将该正则表达式正确传递给 grep？

感谢帮助

将 grep 更改为 egrep 并使用以下格式传递正则表达式并且有效！

proc = subprocess.Popen(['egrep','-C 5', r"Error-|make.*Error", 'file.log'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
