一、用文件名查找文件

# find -name "MyCProgram.c" ./backup/MyCProgram.c ./MyCProgram.c 

 二、用文件名查找文件，忽略大小写

# find -iname "MyCProgram.c" ./mycprogram.c ./backup/mycprogram.c ./backup/MyCProgram.c ./MyCProgram.c 

 三、第二层子目录和第四层子目录之间查找passwd文件

# find -mindepth 3 -maxdepth 5 -name passwd ./usr/bin/passwd ./etc/pam.d/passwd
