贴段代码备忘：

1. # input: list of Entry, to insert head on each of one
   
2. # output: Modify the outputfile ,return 0 if success, -1 if fail.
   
3. #====================
   
4. def printAttr(ls, notTest, outfile='./git-attr.txt'):
   
5.     #outfile = "./git.new-input.txt"
   
6.     fwrite = codecs.open(outfile, 'w')
   
7.     for each in ls:  # each with '\n'.
   
8.         path = each.strip()
   
9.         line = get_file_attr(path)
   
10. 
    
11.         (user_, group_, list_access_) = get_user_attr(path)
    
12.         usr_attr_ = ''
    
13.         for item in list_access_:
    
14.             usr_attr_ += item

16.         # singtax not support:#line = line.insert(6, usr_attr_)  # '_file ' is 5 , insert before index 6.
