python 检索文件内容工具

公司内部需求一个工具检索目录下的文件在另外的目录中使用次数， 用来优化包体的大小。

此代码效率并不高效， 另添加对应的 后缀检索。 用python 实现比较快速， 另还有缺点是只支持 utf-8 格式内容。

各位用到的可以自己摘一下。

（本人习惯使用c\c++，目前发现这种脚本类的确实实现方便，接口齐全， 我能想到的接口， 真的全都有， 用python 写工具， 应该是一个调试起来还可以的过程）

代码如下：

  1 #coding=utf-8
  2 
  3 import os
  4 import sys
  5 import time
  6 
  7 #private:
  8 def checkSuffix(strFileName, strCompareSuffix):
  9     strPreFileName = ''
 10     strFileSuffix = ''
 11     bIsCheckOk = False
 12     strArray = strFileName.split('.')
 13     if len(strArray) > 1:
 14         strPreFileName = strArray[0]
 15         strFileSuffix = strArray[1]
 16     #print(strFileSuffix)
 17     #print(strCompareSuffix)
 18     if strCompareSuffix == '*' or strFileSuffix == strCompareSuffix:
 19         bIsCheckOk = True
 20     return bIsCheckOk, strPreFileName
 21 
 22 def readFileName(file_dir):
 23     for root, dirs, files in os.walk(file_dir):
 24         return files,dirs, root
 25     return '', '', ''

 27 def findString(pathFile, findKey):
 28     #print("open pathFile:", pathFile)
 29     fp = open(pathFile, "r", encoding='utf-8')
 30     strr = fp.read()
 31     if(strr.find(findKey) != -1):
 32         return True

 39             if bIsCheckOk == False:
 40                 #print("fileName", fileName, " is not suffx :", strSuffix)
 41                 continue
