本文介绍了Linux中find命令的使用，包括根据名称查找以mysql开头的文件，结合-exec参数显示文件的基本名称，以及结合-user参数筛选属主为root的文件。这些示例展示了find命令在系统管理中的实用性。

1.-name参数，例：查询/root目录下以mysql开头的文件

[root@zabbix ~]# find /root/ -name "mysql*"
/root/mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar
/root/mysql-community-embedded-5.7.28-1.el7.x86_64.rpm
/root/mysql-community-libs-compat-5.7.28-1.el7.x86_64.rpm
/root/mysql-community-devel-5.7.28-1.el7.x86_64.rpm
/root/mysql-community-embedded-compat-5.7.28-1.el7.x86_64.rpm
/root/mysql-community-libs-5.7.28-1.el7.x86_64.rpm
/root/mysql-community-test-5.7.28-1.el7.x86_64.rpm
/root/mysql-community-common-5.7.28-1.el7.x86_64.rpm
/root/mysql-community-embedded-devel-5.7.28-1.el7.x86_64.rpm
/root/mysql-community-client-5.7.28-1.el7.x86_64.rpm
/root/mysql-community-server-5.7.28-1.el7.x86_64.rpm

2.-name和-exec联合使用，例：查询/root目录下以mysql开头的文件并只显示文件名

-exec后面的参数是查询完对查询目标所执行的命令，这里执行的是basename命令

[root@zabbix ~]# find /root/ -name "mysql*" -exec basename {} \;
mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar
mysql-community-embedded-5.7.28-1.el7.x86_64.rpm
mysql-community-libs-compat-5.7.28-1.el7.x86_64.rpm
mysql-community-devel-5.7.28-1.el7.x86_64.rpm
mysql-community-embedded-compat-5.7.28-1.el7.x86_64.rpm
mysql-community-libs-5.7.28-1.el7.x86_64.rpm
mysql-community-test-5.7.28-1.el7.x86_64.rpm
mysql-community-common-5.7.28-1.el7.x86_64.rpm
mysql-community-embedded-devel-5.7.28-1.el7.x86_64.rpm
mysql-community-client-5.7.28-1.el7.x86_64.rpm
mysql-community-server-5.7.28-1.el7.x86_64.rpm

3.-name和-user联合使用，例：查询/root目录下以mysql开头并且所属用户是root的文件

[root@zabbix ~]# ll /root/
