??最近一段时间在使用CentOS 7.x的时候，有很多地方感觉没有Ubuntu好用，尤其是命令提示符PS1，这里就特意介绍一下如何修改。
编辑配置文件/etc/bashrc
[root@lanzhou ~]# cat /etc/bashrc
# /etc/bashrc# System wide functions and aliases
# Environment stuff goes in /etc/profile# 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.# are we an interactive shell?

[root@lanzhou ~]# 将第42号修改为
[ "$PS1" = "\\s-\\v\\\$ " ] && PS1='\e[32;40m\]\u@\h:\e[36;40m\w \e[33;40m\$ \e[37;40m'
