我的错误

在CentOS中安装jdk时，

修改配置文件，输入命令：

vim /etc/profile

修改完后重新编译，输入命令：

source /etc/profile

我的CentOS错误信息是：-bash:UNset: command not found

-bash:UNset: command not found

解决方法

最后发现了错误原因，将UNset 改为unset。

这样就可以正确编译了。

配置信息

/etc/profile中的信息

# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.
