mysql --prompt一个很好用的命令

想必你们在命令行操做mysql的时候会十分发愁如今的操做的是那个数据库吧，至少我就纠结过，可能您会说我打一条命令不就知道了，是的这样作确实能够的。

但是今儿给你们介绍个好用的命令--prompt

[root@fsailing1 ~]# mysql -uroot -p --prompt="\\u@\\h:\\d \\r:\\m:\\s>"
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

root@localhost:(none) 08:23:32>use test;
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:test 08:23:44>exit;

这样作的好处就是让咱们你们在操做数据库时更加方便快捷。

您也能够在在my.cnf配置文件里进行配置：

[mysql]
prompt=mysql(\\u@\\h:\\d)>

default-character-set=utf8

[root@fsailing1 ~]# vim /etc/my.cnf
[root@fsailing1 ~]# service mysqld restart
