Python Find

It is a python based small utility which finds for given regular expression in all the filenames for the given directory and returns them with full path

How to Use

Just download the package or clone the repo from github.
Run the find.py file with source directory and regular expression to search for given as command line argument.

Example : - py find.py '.' '.*.py'

Find,py

#!/usr/bin/env python3 import sys

import re

import os

# Get the start directory.

start = os.path.normpath(sys.argv[1])

# Get the patterns from the command line arguments.

pattern = sys.argv[2]

# Convert them to regular expressions.

expr = re.compile(pattern)

# Traverse the directory for all the files.

for root, dirs, files in os.walk(start):

for fname in files:

# If a file matches the pattern then print its name.

if expr.search(fname):

print(os.path.join(root, fname))
