以所有者身份运行程序，怎么不好使呢？

请各位帮兄弟看看：

2. dave@debian:~/bin$ ls -l
3. total 16
4. -rwsr-xr-x 1 root root 100 2008-11-13 20:10 home_wired
5. -rwsr-xr-x 1 root root 103 2008-11-13 20:06 home_wireless
6. -rwsr-xr-x 1 root root 102 2008-11-13 20:09 office_wired
7. -rwsr-xr-x 1 root root 106 2008-11-13 20:09 office_wireless
8. dave@debian:~/bin$ cat home_wireless
9. #! /bin/bash
11. ln -sf /etc/network/home_wireless /etc/network/interfaces
12. /etc/init.d/networking restart
13. dave@debian:~/bin$ ./home_wireless
14. ln: cannot remove `/etc/network/interfaces': Permission denied
15. Reconfiguring network interfaces...ifdown: failed to open statefile /etc/network/run/ifstate: Permission denied
16. ifup: failed to open statefile /etc/network/run/ifstate: Permission denied
17. failed.
18. dave@debian:~/bin$

复制代码

但是

2. sudo ./home_wireless

复制代码

就可以？

是不行，错误明确：/etc/network/run/ifstate: Permission denied -- 只有root可以，所以sudo就可以。

解决。
s权限只能在二进制文件上使用，脚本不行。
