mysql prompt的用法詳解

--prompt=name 我們登入mysql數據庫后，mysql的提示符只是一個很簡單內容 mysql> ,沒有其他任何信息。

通過--prompt=name可以自定義提示信息，通過配置顯示登入的主機地址，登陸用戶名，當前時間，當前數據庫等。

參數如下:

\d The default database
\h The server host

\n? A newline character
\O? The current month in three-letter format (Jan, Feb, …)
\o? The current month in numeric format
\P? am/pm
\p The current TCP/IP port or socket file
\R? The current time, in 24-hour military time (0–23)
\r? The current time, standard 12-hour time (1–12)
\S? Semicolon
\s? Seconds of the current time
\t? A tab character
\U???

\u Your user name
\v? The server version
\w? The current day of the week in three-letter format (Mon, Tue, …)
\Y? The current year, four digits
