Linux误删etc下的profile,Linux centos 7 的/etc/profile 被我改坏了 忘记原来是什么样的了，怎么恢复？…

系统版本：Linux linuxCentOS7 3.10.0-862.6.3.el7.x86_64 #1 SMP Tue Jun 26 16:32:21 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

这是第一次改这个文件，所以谁有默认的能发给我一份吗？

下面是我当前/etc/profile的内容，我只是在最后加个环境变量(后来为了恢复删了)

# /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.

在执行source /etc/profile 的时候 一直报错：

使用/bin/vim /etc/profile 删除了自己加的两行，重新加载也还是一样的错误。可能我误动了其他地方。大家能帮我恢复正常吗？
