mysql 控制臺程序的提示符 prompt 字符串設(shè)置，學(xué)習(xí)mysql的朋友可以參考下。
The prompt command reconfigures the default mysql> prompt. The string for defining the prompt can contain the following special sequences.

mysql 控制臺程序的默認提示符為 "mysql>". 該提示符可用根據(jù)需要進行修改設(shè)置:

有以下幾種設(shè)置方式:

設(shè)置shell 的環(huán)境變量 : MYSQL_PS1

shell> export MYSQL_PS1="(\u@\h) [\d]> "

使用程序啟動命令選項 : --prompt

shell> mysql --prompt="(\u@\h) [\d]> "
(user@host) [database]>

設(shè)置選項文件中的 [mysql] 節(jié),添加 prompt 選項

[mysql]
prompt=(\\u@\\h) [\\d]>\\_
在 mysql 程序中使用 prompt (\R) 命令

mysql> prompt (\u@\h) [\d]>\_
PROMPT set to '(\u@\h) [\d]>\_'
(user@host) [database]>
(user@host) [database]> prompt
Returning to default PROMPT of mysql>
mysql>
