Used in the Rootstalk project to sanitize filenames

change-filenames.py

import os

"""
Renames the filenames within the same directory to be Unix friendly
(0) Removes "Volume V, Issue 1, "
(1) Makes lowercase (not a Unix requirement, just looks better ;)
(2) Changes spaces, colons, apostrophes, underscores and exclaimation points to hyphens
(3) Removes commas and semi-colons
(4) Replaces doubled hyphens and doubled periods with singles
(5) Replaces ".-" with "-" and "-." with "."


Usage:
python change-filenames.py
"""

path =  os.getcwd()
filenames = os.listdir(path)

for filename in filenames:
  os.rename(filename, filename.replace("Volume V, Issue 1, ", "").lower())
for filename in filenames:
  os.rename(filename, filename.replace(" ", "-").replace(",", "").replace(";", "").replace(":", "-").replace("'", "-").replace("!", "-").replace("_", "-").replace("--", "-").replace("..", ".").lower())
for filename in filenames:
  os.rename(filename, filename.replace("--", "-").replace("..", ".").replace(".-", "-").replace("-.", "."))
