修改linux服务器的文件，建议先备份，再进行修改

如果不小心把此文件破坏了，想恢复，可以先把源文件备份，将源文件内容删除，下面内容重新粘贴即可

# /etc/profile
    
    # 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.
