Linux 更改命令提示符

1. 更改前，提示符显示主机的名字，超长不好看

2. 在.bashrc 文件后面增加一行 ：export PS1='[e[34;44m]]$ '  ，重新登录，提示符只保留了$符号。

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi

# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=

# User specific aliases and functions

export PS1='[e[34;44m]]$ '
#export PS1='[[e[34;44m]u@w]$ '
