可以exclude 特定目錄的copy 程式

因為之前有同事說Linux  下的cp 無法排除特定目錄，所以我就用python2.7 寫了隻  ohCP
給他用

#!/usr/bin/python2.7
import os,time,shutil,argparse,sys
def exculde_cp(source,dest,exclude):
print(source)
if os.path.isdir(source) == True or os.path.isfile(source)==False:
print(source)
dirnames=os.listdir(source)
for dirname in dirnames:
print(dirname)
srcname=os.path.join(source,dirname)
dstname=os.path.join(dest,dirname)
try:
if srcname == exclude:
pass
elif os.path.islink(srcname):
print('detect dirs has some links')
linkto = os.readlink(srcname)
os.symlink(linkto, dstname)
else:
print('begin copy dir',dirname)
shutil.copytree(srcname,dstname)

except (IOError, os.error) as why:
print('some errors',why)
elif os.path.isdir(source) == False or os.pathisfile(source):
try:
shutil.copy2(source,dest)
except (IOError, os.error) as why:
print('some errors',why)
