1.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


2.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

3.


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。


4.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.
