# this is a python util to modify file names, replace substring in file/folder name with another substring, recursively.
# you should modify variable 'basic_dir' / 'c' / 'c_new', before run this script
# everything, include file/folder recurisively, under the 'basic_dir' will be rename,
# how to run this script, just "./xxx.sh"

# ps: backup before modify is good manners.

import os
import shutil

# basic dir to where files resides
basic_dir = "/tmp/test/"
# substring to replace
c = " "
# new substring
c_new = " "

# function to modify file name recursively

	# check whether the 2 substring are the same
	if c == c_new:
		print ("2 substring are the same, no need to change")
		return True
	# add '/' to dir end, if necessary,
	if not dir.endswith('/'):
		dir += '/'
	# check dir exists
	if os.path.isdir(dir):  
		print ("dir is: "+dir)
	else:
		print ("dir not exist:" + dir) 
		return False

	# file list
	filelist=[]
	filelist=os.listdir(dir)

	# iterator filelist
	for fname in filelist:
		# change file name if need
		if fname.find(c) >= 0:
			fname_new=fname.replace(c, c_new)   
			print fname_new
			shutil.move(dir+fname,dir+fname_new)
			fname = fname_new

		# call the function recurisively on the sub dir
		if os.path.isdir(dir+fname):
			modify_name(dir+fname,c,c_new)

# the entry, call the function, with the basic dir
