prompt命令可以在mysql提示符中显示当前用户、数据库、时间等信息

登录的时候设置

mysql -uroot -p --prompt="\u@\h:\d \r:\m:\s>"

配置文件中设置

[mysql]
prompt=mysql(\u@\h:\d)>
default-character-set=utf8
\u:连接用户
\h:连接主机
\d:连接数据库
\r:\m:\s:显示当前时间

[mysql]
#prompt="\U/\R:\m[\d]>"
#prompt=[\u@\p][\d]>\_
prompt="\u@\h:\d \R:\m>"

动态调整
mysql> prompt (\u@\h) [\d]>_
PROMPT set to ‘(\u@\h) [\d]>_’
(root@localhost) [(none)]>
