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

>>> 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[1])
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

no no no. geek is when you spend hours to find how to do in bash scripting since it’s, by logic, the right thing to do

for f in *; do mv “$f” `echo $f | tr ‘ ‘ ‘_’`; done

BUT – I like python too much!

Well it is interesting, certification
and what can I say to it but it doesn’t agreed me cent by cent.

In Ubuntu, at least:
rename ‘y/ /_/’ *
rename is a perl script using perl regex. Therefore:
“y/{0}/{1}/”: Search list for all occurrences of {0} and substitute by {1}
* : Feeds all files in current dir

Do you have an outdoor space that you dream of entertaining in but it is lacking that certain something that makes it a place that you want to be? If so, there are some simple things that you can do to make the space your very own.
Thanks for the code snippet. I had to alter it, because as is it will rewrite all files in a directory regardless if they have spaces or not. This includes hidden files, which can be dangerous. Here’s my much more verbose version.
#!/usr/bin/pythonimport osimport sys files = os.listdir(sys.argv[1])for f in files: if f[0] == ‘.’: print(‘Skipping ‘+f) continue if ‘ ‘ in f: skip = raw_input(‘Replacing ‘+f+’. Hit enter to continue or type s to skip: ’) if not skip: print(f+’ -> ‘+f.replace(‘ ‘, ‘_’)) os.rename(f, f.replace(‘ ‘, ‘_’)) else: print(‘Skipping ‘+f)
Thanks for the code snippet. I had to alter it, because as is it will rewrite all files in a directory regardless if they have spaces or not. This includes hidden files, which can be dangerous. I just filtered for f[0] != ‘.’ and ‘ ‘ in f.
