finding/displaying directories by size

[fastopa]

I have looked at many of the post regarding finding/displaying files by size. Though I have not found anything specific

to directories. I have tried using the same logic for files for directories but without much luck.

Here is what I am trying to do.

I have a directory that has 3 levels of subdirectories. I would like to display the 3rd level of subdirectories with

their size but only the ones that are larger than 20MB. Doesn't really matter if I see the 1st and 2nd level directories

as well.

Here is what I have tried:

users# find -maxdepth 3 -type d -size +20M -ls

I get back

users#
(no error message - and I know there are many folders larger than 20MB in this folder)

If I take out the "-size +20M" it returns me all the directories in the first 3 levels.

I also tried using the du command, however there does not seem to be the option for specifying sizes

du --max-depth 3 -h

This gives me a nice display but, again, all the directories.

Any help would be appreciated.

The reason the '-size +20M ' option didn't work is because it's checking the size of the directory file itself, not the total amount of space used within the directory.

What I would do is use the 'du' command to determine the space used by a directory and then pipe the output from find to awk to select the directories you want.

find -maxdepth 3 -type d -exec du -sm {} \; | awk '($1 > 20) {print $0}'

Thank you very much!

That is exactly what I was looking for.
