# Python 修正由于文件夹迁移导致符号连接错误的问题

FORMER_ROOT 为原文件夹路径，CURRENT_PATH 为新路径。例如，原来文件保存在 /home/usr/FormerPath 下，将其移动到 /home/usr/CurrentPath 路径下后，CurrentPath 下的符号连接文件，尤其是使用绝对路径进行连接的文件其指向路径还在 /home/usr/FormerPath 下，使用下列脚本可对其进行修复。

```python
#!/usr/bin/python
# -*- coding: utf-8 -*-

import os

FORMER_ROOT = "/home/usr/FormerPath"
CURRENT_PATH = "/home/usr/CurrentPath"

def procSLink(path):
    lndir = os.readlink(path)
    if lndir.startswith(FORMER_ROOT):
        print "Proc SymFile: "+path
        print "Sym To: "+lndir
        lndir = lndir[len(FORMER_ROOT):]
        npath = CURRENT_PATH+lndir
        print "New Symb:"+npath
        os.remove(path)
        os.symlink(npath, path)


def procDir(path):
    files = os.listdir(path)
    for f in files:
        file = path + '/' + f
        if(os.path.islink(file)):
            procSLink(file)
        if(os.path.isdir(file)):
            procDir(file)


procDir(CURRENT_PATH)
```
