本文介绍如何利用Linux下的find命令按特定目录层级查找文件。通过设置mindepth和maxdepth参数，可以精确控制搜索的深度范围，例如仅在一、二级目录中查找passwd文件，或是在更深的目录层级中进行搜索。

Limit Search To Specific Directory Level Using mindepth and maxdepth

Find the passwd file under all sub-directories starting from root directory.

# find / -name passwd
./usr/share/doc/nss_ldap-253/pam.d/passwd
./usr/bin/passwd
./etc/pam.d/passwd
./etc/passwd

Find the passwd file under root and one level down. (i.e root — level 1, and one sub-directory — level 2)

# find -maxdepth 2 -name passwd
./etc/passwd

Find the passwd file under root and two levels down. (i.e root — level 1, and two sub-directories — level 2 and 3 )

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

Find the password file between sub-directory level 2 and 4.

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