mysql自定义命令行提示prompt

官方资料入口

　　在《MySQL 5.7 Reference Manual》的如下章节可以看到自定义命令提示的描述：

　　https://dev.mysql.com/doc/refman/5.7/en/mysql-commands.html

　　MySQL 5.7 Reference Manual -->Chapter 4 MySQL Programs -->4.5 Client Programs -->4.5.1 mysql — The MySQL Command-Line Client -->4.5.1.2 mysql Client Commands

PROMPT自定义实践

　　官方给出有4种方式可以实现命令行自定义。

　　1、调整系统环境变量，使用MYSQL_PS1　　

[mysql@zsdb script]$ export MYSQL_PS1="(\u@\h) [\d]> "       <=======MYSQL_PS1
[mysql@zsdb script]$ ./m3306.sh 
。。。。。。。
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

(root@localhost) [(none)]> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
(root@localhost) [mysql]> 

　　2、在mysql命令使用--prompt参数

[mysql@zsdb script]$ /u01/mysql5.7/svr/bin/mysql --prompt="(\u@\h) [\d]> " -uroot --socket=/u01/mysql5.7/run/my3306/mysql.sock -p123456
。。。。。。。
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

(root@localhost) [(none)]> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
(root@localhost) [mysql]>

　　3、编辑*.cnf文件，添加prompt选项

　　[mysql]

　　prompt=(\\u@\\h) [\\d]>\\_　　

[mysql@zsdb script]$ ./m3306.sh 
。。。。。
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

(root@localhost) [(none)]> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
(root@localhost) [mysql]> 

　　4、sql交互窗口使用prompt　　

[mysql@zsdb script]$ ./m3307.sh 
。。。。。。
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> prompt (\u@\h) [\d]>\_        <======= 参数调整
PROMPT set to '(\u@\h) [\d]>\_'
(root@localhost) [(none)]> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
(root@localhost) [mysql]>
