我今天遇到了一个严重的问题：当我ifconfig在 ubuntu 12.04 上输入时，它没有显示 ip 配置。谁可以帮我这个事？
这是结果ifconfig：
Command 'ifconfig' is available in '/sbin/ifconfig'
The command could not be located because '/sbin' is not included in the PATH environment variable.
This is most likely caused by the lack of administrative privileges associated with your user account.
ifconfig: command not found
我想更改放置在我桌面上的二进制文件的图标。二进制文件与 unetbootin 相关。我想从桌面执行 unetbootin 所以我想更改图标。
我怎样才能做到这一点？
