How to delete files in a directory without deleting folders?

Question

linux

There are directories with a file, let's say there are directories that make up the path /dir1/dir2/dir3/. How to delete files in all directories without deleting the directories themselves?

A similar command rm -f /path/to/directory/{*,.*}cannot be deleted, files are deleted only in one directory.

Answer 1

find /dir1 -type f -delete
Find in the folder /dir1and deeper all occurrences of the type "file" ( -type f) and delete them ( -delete)
