os.walk

import os,sys
for root, dirs, files in os.walk("."):
for f in files:
fullpath = "%s/%s" % (root, f)
if fullpath.endswith("java"):
print fullpath
#os.system("dos2unix " + fullpath)
temp = fullpath[:-1]
#command = "expand -t 4 " + fullpath + " > " + temp
command = "rm -rf " + fullpath
command = "sed -i 's/ *$//' " + fullpath
#print command
os.system(command)
