我竟然是这样在Ubuntu上安装REALPLAYER的

不再尝试什么 chmod a +x 之类的无用的命令了，我的终端没有继续安装的提示。看我小帆是如何安装的（系统是 UBUNTU 7.10 ALPHA 5)：

1.将下载到的 REALPLAYER10GOLD.BIN 放进去主文件夹；

2.进入主文件夹，在 REALPLAYER10GOLD.BIN 上右键--复制；

3.这时候才打开终端，先输入 sudo，然后粘贴，对，粘贴！然后回车！然后按照提示一步一步的安装下去就OK了。

附安装记录
sailxia@sailxia-desktop:~$ chmod a+x RealPlayer10GOLD.bin
sailxia@sailxia-desktop:~$ RealPlayer10GOLD.bin
bash: RealPlayer10GOLD.bin：找不到命令
sailxia@sailxia-desktop:~$ sudo /home/sailxia/RealPlayer10GOLD.bin
