终端提示符设置

当前用户账号@主机名 当前所在位置 # / $。 如 ：root@www ~ # 代表的是：root用户，主机名为www，以及当作在根目录下，超级用户后面显示的就是#，一般用户后面显示的是$。 在用户的 ~/.bashrc 文件中修改 PS1 环境变量设置即可。 要去除前面的路径、用户名及主机名显示，只保留命令提示符，可以这样设置：

export PS1='samy$ ' source .bashrc

命令及立即生效命令

cat .zshrc
source .zshrc

配置备份

.zshrc

# You can set one of the optional three formats:

# Example format: plugins=(rails git textmate ruby lighthouse)
