How to do a mass rename?

Question

I need to rename files names like this

transform.php?dappName=Test&transformer=YAML&v_id=XXXXX

to just this

XXXXX.t

You may use whatever you want to transform the name (perl, sed, awk, etc.). I'll use a python one-liner:

for file in 'transform.php?dappName=Test&transformer=YAML&v_id='*; do 
    mv $file `echo $file | python -c "print raw_input().split('=')[-1]"`.txt;
done

Here's the same script entirely in Python:

import glob, os
PATTERN="transform.php?dappName=Test&transformer=YAML&v_id=*"

for filename in glob.iglob(PATTERN):
      newname = filename.split('=')[-1] + ".txt"
      print filename, '==>', newname
      os.rename(filename, newname)

Side note: you would have had an easier life saving the pages with the right name while grabbing them...
