Question

I have written a Python Script to find out lines containing a particular script from each of the files within a directory. It works fine if i make this script run in the directory having those files.

#!/usr/bin/env python
import os

def searchthis(location, searchterm):
    for fname in os.listdir(location):
        fullpath = os.path.join(location, fname)
        for line in file(fullpath):
            if searchterm in line:
                print line



searchthis(os.getcwd(), "mystring")

Is there any way I could do this with os.walk and search for recursively in each of the files present in all the directories as well as subdirectories.

Answer 1

#!/usr/bin/env python

import os

def searchthis(location, searchterm):
   for dir_path, dirs, file_names in os.walk(location):
      for file_name in file_names:
         fullpath = os.path.join(dir_path, file_name)
         for line in file(fullpath):
            if searchterm in line:
                print line

searchthis(os.getcwd(), "mystring")
