HP-UX执行swinstall报错

使用swinstall安装depot包时报错，GUI或TUI无法启动，设置了LANG=C仍然不行。

host1[#/]export LANG=C
host1[#/]swinstall -s /tmp/jdk.depot
NOTE:    The interactive UI was invoked, since no software was
         specified

ERROR:   Either Graphic User Interface(GUI) or Terminal User
         Interface(TUI) cannot be started. In order to execute this
         command, you have to modify your DISPLAY or use English
         version TUI with LANG="" or LANG=C.

检查了环境变量，发现设置了以下环境变量：
LC_ALL=zh_CN.GB18030
将该环境变量unset，重新执行swinstall即可。
unset LC_ALL
