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)

How to use python replace a word as sed does

import os,fileinput 
changing_file_dst='/Users/Hermes/Downloads/srt.txt' changefile=fileinput.input(changing_file_dst, inplace=1)
 # <==this is part very import if you just fileinput.input(change_file_dst) data will not modified , so you need set inplace=1 to modify current file 
for st in changefile:
 replace_str='cluster.enabled=true'
 pattern='cluster.enabled=false'
 result=st.replace(pattern,replace_str)
 print(result) changefile.close()

 original I just want use open , but when I write all file will be truncate and write . so I use fileinput.
原本是用open 將檔案 打開修改可是用 W mode 會因為先作truncated , 再寫入所以檔案會被清空 ，所以改用 fileinput 直接作修改
