Recursive rename in python script


#!/usr/bin/env python
import fnmatch
import os

 root = os.getcwd()
pattern = "*.JPG"

 for root, dirs, files in os.walk(root):
    for filename in fnmatch.filter(files, pattern):
        #print (os.path.join(root, filename))
        full_src = os.path.join(root, filename)
        full_dst = full_src.replace('.JPG','.jpg')
        os.rename(full_src, full_dst)
        print "Renaming {0} to {1}".format(full_src, full_dst)

Codes 1-127 are typically generated by your job itself calling  exit()  with a non-zero value to terminate itself and indicate an error. In BaBar we don't make very much use of this. The most common such value you might see is 64, which is the value used by Framework to say that its event loop is being stopped before all the requested data have been read, typically because time ran out. In recent BaBar releases you might also see 125, which we use as a code for a generic "severe error"; the job log should contain a message stating what the error was. Exit codes in the range 129-255 represent jobs terminated by Unix " signals ". Each type of signal has a number, and what's r
