Pythonでlinuxのfindのようなファイル検索

いつも忘れるので，メモ．

myfind.py

import os
import fnmatch
import argparse

# parsing arguments
parser = argparse.ArgumentParser()
parser.add_argument('path', type=str, default=None,
    help="Directory for searching files.")
parser.add_argument('-n', '--name', type=str, default='*',
    help="Pattern for searching files.")
args = parser.parse_args()

# search
files = list()
for root, dirs, names in os.walk(args.path):
    new_files = [ os.path.join(root, f) for f in names
        if fnmatch.fnmatch(os.path.join(root, f), args.name) ]
    files.extend(new_files)

# print
for f in files:
    print f

# ls -F .
hoge/   uga/    ponyo.txt
# ls -F hoge
hogera.py   honyara.sh
# ls -F uga
uga.sh      ugera.py
# python myfind.py . --name "*.py"
./hoge/hogera.py
./uga/ugera.py
