Centos命令行报bash:.....:command not found的解决办法

Uset: command not found

解决centos提示：-bash:man:command not found

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。
