经常会遇到下载的文件或电子书，名字中间都包含了一些网址信息，实际使用中由于名字太长不方便，下面的脚本使用正则表达式来对目录下的所有文件重命名：
例如：
修改前：[大家网]Mac OS X for Unix Geeks[www.TopSage.com].mobi
修改后：Mac OS X for Unix Geeks.mobi
修改后：Mac OS X for Unix Geeks.mobi
python代码如下
import os
import re
def rename_dir(dir,regex,f):
if not os.path.isdir(dir) or not os.path.exists(dir) :
print("The input is not one directory or not exist.")
for root,subdirs,files in os.walk(dir):
for name in files:
oldname = name
newname = re.sub(regex,f,name)
print("Before : " + os.path.join(root,oldname))
print("After : " + os.path.join(root,newname))
if not name == newname and not os.path.exists(os.path.join(root,newname)):
os.rename(os.path.join(root,oldname),os.path.join(root,newname))
for dir in subdirs:
rename_dir(os.path.join(root,dir))
rename_dir("C:\\Python31\\test","\[.*\](.*)\[www.TopSage.com\](.*)",lambda m:m.group(1)+m.group(2))
import re
def rename_dir(dir,regex,f):
if not os.path.isdir(dir) or not os.path.exists(dir) :
print("The input is not one directory or not exist.")
for root,subdirs,files in os.walk(dir):
for name in files:
oldname = name
newname = re.sub(regex,f,name)
print("Before : " + os.path.join(root,oldname))
print("After : " + os.path.join(root,newname))
if not name == newname and not os.path.exists(os.path.join(root,newname)):
os.rename(os.path.join(root,oldname),os.path.join(root,newname))
for dir in subdirs:
rename_dir(os.path.join(root,dir))
rename_dir("C:\\Python31\\test","\[.*\](.*)\[www.TopSage.com\](.*)",lambda m:m.group(1)+m.group(2))
