BASH - limit depth of directory loop

Question

How can I loop through directories and restrict the depth to only 3 levels? My version of find does not have -maxdepth. I'd like to keep it to one line if possible.

e.g: find /data -type d -print

Any help would be much appreciated. Thanks.

shopt -s nullglob
for d in /data/*/ /data/*/*/ /data/*/*/*/
do
  echo "$d"
done

It doesn't do the -type d though; using [ -d "$d" ] && echo "$d" would, and you could drop setting nullglob then.

@user2719058: The terminating slash makes sure that it does, for the most part.

@IgnacioVazquez-Abrams: Ah, I stand corrected. Indeed, I didn't think about the slashes. What do you mean by "for the most part"? I can't think of cases where it doesn't work.

@user2719058: It will also include symlinks to directories.
