This is merely my personal note. I was about to rename all my files under a directory. I need to replace the space with underscore character
('_'). My first thought was a simple bash script to do that. Apparently, it’s been very long time since my last bash coding session. I spent 15 minutes reading how to read all files and rename them. And I got nothing.
Luckily, I know python. Stupid me. Why didn’t I think it at first time. It was couple minutes of python and all the spaces were replaced by underscores. Thanks to python. All I did were
$ python Python 2.5.2 (r252:60911, Oct 5 2008, 19:24:49) [GCC 4.3.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import os >>> files = os.listdir('./') >>> for f in files: ... os.rename(f, f.replace(' ', '_')) ... >>>
Or if you want to save in a script, you could you this
#!/usr/bin/python import os import sys files = os.listdir(sys.argv) for f in files: os.rename(f, f.replace(' ', '_'))
The script takes the directory path as the argument. You could modify the script to use regex to have a better rename rule
