使用python的chardet库获得文件编码并修改编码
首先需要安装chardet库，有很多方式，我才用的是比较笨的方式：sudo pip install chardet
代码如下:
#!/usr/bin/env python
# coding: UTF-8
import sys
import os
import chardet
def print_usage():
print '''usage:
change_charset [file|directory] [charset] [output file]\n
for example:
change 1.txt utf-8 n1.txt
change 1.txt utf-8
change . utf-8
change 1.txt
'''
def get_charset(s):
return chardet.detect(s)['encoding']
def remove(file_name):
os.remove(file_name)
def change_file_charset(file_name, output_file_name, charset):
f = open(file_name)
s = f.read()
f.close()
if file_name == output_file_name or output_file_name == "":
remove(file_name)
old_charset = get_charset(s)
u = s.decode(old_charset)
if output_file_name == "":
output_file_name = file_name
f = open(output_file_name, 'w')
s = u.encode(charset)
f.write(s)
f.close()
def do(file_name, output_file_name, charset):
if os.path.isdir(file_name):
for item in os.listdir(file_name):
try:
if os.path.isdir(file_name+"/"+item):
do(file_name+"/"+item, "", charset)
else:
change_file_charset(file_name+"/"+item, "", charset)
except OSError, e:
print e
else:
change_file_charset(file_name, output_file_name, charset)
if __name__ == '__main__':
length = len(sys.argv)
if length == 1:
print_usage()
elif length == 2:
do(sys.argv[1], "", "utf-8")
elif length == 3:
do(sys.argv[1], "", sys.argv[2])
elif length == 4:
do(sys.argv[1], sys.argv[3], sys.argv[2])
else:
print_usage()
