Linux 命令行报错：-bash:XXX: command not found ，解决方法参考

相关错误

在网上搜索了类似的错误解决方法，错误虽然不同，但解决办法可以学习一下。

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。

# 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.
