1 -maxdepth levels  设置最大目录层级；
 2 Descend  at  most levels (a non-negative integer) levels of directories below the com-
 3 mand line arguments.  -maxdepth 0
 4 means only apply the tests and actions to the command line arguments.
 5 
 6 -mindepth levels 设置最小目录层级；
 7 Do not apply any tests or actions at levels less than levels (a non-negative integer).
 8 -mindepth 1 means process all files except the command line arguments.
 9 
10 -name pattern 指定字符串作为寻找文件或目录的范本样式；
11 
12 -size  指定文件大小

23        links when -L is in effect, use -xtype.

1 找出当前目录下所有root的文件，并把所有权更改为用户tom 
2 find .-type f -user root -exec chown tom {} \; 
3 上例中，{} 用于与-exec选项结合使用来匹配所有文件，然后会被替换为相应的文件名。 找出自己家目录下所有的.txt文件并删除 
4 find $HOME/. -name "*.txt" -ok rm {} \; 
5 上例中，-ok和-exec行为一样，不过它会给出提示，是否执行相应的操作。 查找当前目录下所有.txt文件并把他们拼接起来写入到all.txt文件中
6  find . -type f -name "*.txt" -exec cat {} \;> all.txt 
7 将30天前的.log文件移动到old目录中
8  find . -type f -mtime +30 -name "*.log" -exec cp {} old \;
