This does grep through all the files and is very fast because the regex is compiled in Python , rather than sitting in some directory as an external command. That is where the optimization comes in.

Re: Regex Python Help
Grep is regular expressions. If I'm using Python, I'll use the Python modules.

Basic Python V3 Search Tool using RE module
This basic script will help to find
evidence of CryptoWall on a slave drive. Although it is
just a string, more complex regex patterns can be
replaced with the string. It is incredible how fast Python is and
how easy it has helped in quickly assessing a pool of slave drives.
I'm improving it as we speak.
Thanks for your help and patience. I'm new with Python.
import os
import re
# From the Root
topdir = "."
# Regex Pattern
pattern="DECRYPT_I"
regexp=re.compile(pattern)
for dirpath,dirnames, files in os.walk(topdir):
for name in files:
result=regexp.search(name)
print(os.path.join(dirpath,name))
print (result)

No worries Steven, Thanks to ALL on this thread.

Re: Regex Python Help
Here you go. Windows shell was easier!!! for /f %a in (c:\gonow) do echo %a | c:\Python34\python c:\python34\unopy.py %a Now I can use any regex pattern, I need.

Re: Regex Python Help
This works fine , but I have to pipe the filename to the script python stool
I am creating a tool to search a filesystem for one simple string.

Re: Regex Python Help
Thank you! But
The print error is gone, but now the script quickly finishes and doesnt walk
the OS tree or search.

Re: Regex Python Help
Thank you Gary, that got rid of the error, but now there is no tree walk, it
runs and immediatley finishes. I just need to grep each file. I have this
working with the windows "for /r %a and redirecting that to Python, but want to
use Python only. I do have dummy files with the regex string.
Thanks again,
Gregg
