[SOLVED] Show directory path with only files present in them

Issue

This is the folder structure that I have.

Using the find command find . -type d in root folder gives me the following result

Result

./folder1
./folder1/folder2
./folder1/folder2/folder3

However, I want the result to be only ./folder1/folder2/folder3. i.e only print the result if there's a file of type .txt present inside.

Can someone help with this scenario? Hope it makes sense.

Solution

find . -type f -name '*.txt' |
sed 's=/[^/]*\.txt$==' |
sort -u

Find all .txt files, remove file names with sed to get the parent directories only, then sort -u to remove duplicates.

This won’t work on file names/paths that contain a new line.
