示例脚本(感谢Bill Karwin的–user和–password注释！)：
#!/bin/bash ## --user=XXXXXX --password=XXXXXX *may* not be necessary if run as root or you have unsecured DBs but ## using them makes this script a lot more portable. Thanks @billkarwin RESULT=`MysqLshow --user=XXXXXX --password=XXXXXX myDatabase| grep -v Wildcard | grep -o myDatabase` if [ "$RESULT" == "myDatabase" ]; then echo YES fi
这些是在提示符下运行时命令的样子：
[root@host ~]# MysqLshow myDatabase Wildcard: myDatabase +------------------+ | Databases | +------------------+ | myDatabase | +------------------+
如果不存在DB,则输出如下所示：
[root@host ~]# MysqLshow myDatabase Wildcard: myDatabase +-----------+ | Databases | +-----------+ +-----------+
然后,解析输出并根据它是否存在执行您需要的操作！
