Finding last depth directories inside all directories with the same name

Question

I already saw the question: Finding subdirectories inside all directories with the same name

Now my directory structure is:

$ find .

.
./4
./4/1
./2
./2/1
./5
./5/1
./1
./1/1
./3
./3/1

I want to list all the directories at the end with "1" in their name:

./4/1
./2/1
./5/1
./1/1
./3/1

but I don't want

./1

I have tried the following commands:

find . -name "*1*"
find . -type d -path '*/1*'
find . -path '*/1*' -depth 2 -type d
find . -depth 2 -path '*/1*' -type d

UPDATE

find . -depth 2

gives the error:

find: paths must precede expression: 2

Found my solution

find -mindepth 2 . -type d -path "*1*"

Can anybody explain why -depth didn't work while -mindepth worked ?

Answer 1

Answer

find -mindepth 2 . -type d -path "*1*"

Explaination found here

— Option: -maxdepth levels

Descend at most levels (a non-negative integer) levels of directories below the command line arguments. ‘-maxdepth 0’ means only apply the tests and actions to the command line arguments.

— Option: -mindepth levels

Do not apply any tests or actions at levels less than levels (a non-negative integer). ‘-mindepth 1’ means process all files except the command line arguments.

— Option: -depth

Process each directory's contents before the directory itself. Doing this is a good idea when producing lists of files to archive with cpio or tar. If a directory does not have write permission for its owner, its contents can still be restored from the archive since the directory's permissions are restored after its contents.

I got confused between these options.
