python文件内容如下：
#
-*- coding: cp936 -*-
import
os ,string ,urllib ,operator
#
文件替换目录路径
sdir='/usr/local/mldonkey/incoming/'
#
数字标记
sNum='0123456789'
#
遍历目录做文件名转换
def
convert():
filenames=os.listdir(sdir)
for filename in filenames :
if filename != convertName(filename)
:
print filename + '
>>> ' + convertName(filename)
os.rename(sdir + filename
,sdir + convertName(filename))
#
转换一个文件名
def
convertName(s) :
location = 0
ret = ""
while True :
if location + 8 <= len(s) :
subStr = s[location:location + 8]
if check(subStr) :
ret += "%" +
hex((int)(subStr[1:4]))[2:4] + "%" + hex((int)(subStr[5:8]))[2:4]
location = location + 8
else :
ret += s[location :location +
1]
location = location + 1
else :
ret += s[location:]
break
return urllib.unquote(ret)
#
检查一个字符串是否需要做转换
def
check(s):
if len(s) != 8 :
return False
if s[0] != '_' or s[4] != '_' :
return False
if (s[1] in sNum) and (s[2] in sNum) and
(s[3] in sNum) and (s[5] in sNum) and (s[6] in sNum) and (s[7] in sNum) :
return True
return False
#
执行文件名转换
convert()
要运行此脚步，需要Python2.4，在命令行输入：
python mldonkey.py
运行即可。
