mysql --prompt

mysql --prompt修改命令行鏈接mysql時的提示符，shell腳本示例如下

#!/bin/bash

case $1 in
    crm) cmd='mysql  -h192.168.1.2 -uroot -proot -P3306 -Dcrm'
;;
*)
    echo "數據庫變量不存在:$1 僅支持輸入 crm"
    exit 0
;;
esac
shift 1
$cmd --prompt="[\u@\h:\p(\d) \R:\m:\s] mysql>" --default-character-set=utf8 -A "$@"

在命令行輸入 db crm 執行效果如下

liuzhao ~ $ db crm
