Unix utility find allows many arguments. Here is how one can limit searched directories. Arguments -maxdepth and -mindepth should be used first before let’s say -name or -type.
Let’s created four sub directories to investigate how it works:
$ mkdir -p a/b/c/d
$ find a
a
a/b
a/b/c
a/b/c/d
$ find a -maxdepth 2
a
a/b
a/b/c
$ find a -maxdepth 2 -mindepth 2
a/b/c
$ find a -mindepth 2
a/b/c
a/b/c/d
