这篇博客介绍了如何在Python中使用sys.argv传递命令行参数，并详细讲解了如何利用os.walk进行文件递归搜索。文章提醒在处理含有特殊字符的参数时需要注意转义，并给出了相关代码示例。

使用sys.argv可以传递参数
sys.argv[0]表示代码本身文件路径
所以传入的文件从sys.argv[1]，开始算起，传入内容大概是以空格进行分割

有时传入的内容中，有特殊字符，注意用反斜线转义

输入命令，如下

    find_case.py '\\CLK38M_PROC\[115\].U_CLK38M_2FF_SYNC.INST_COMMON_SYNC_SVA_CHK .ipdb_common_sync_glitch_chk'

或者

phthon change.py /home/eagle2.work/regression_simfab/log

code如下

import sys
root=sys.argv[1]

或者，全代码


#!/usr/bin/env python

import os
import re
import sys

checker_log =sys.argv[1]
root='/home/eagle2.work3/regression_simfab/XG756_C0/XG756_C0_SPEC_3_3_SOC_TB_sva_case_search'

    global check_file2

    for rt,dirs,files in os.walk(root):#ergodic the files in path root
