Finding directories inside a folder and deleting if smaller than a certain size?

rated 0 times [ 1] [ 0] / answers: 1 / hits: 1603 / 2 Years ago, tue, april 19, 2022, 1:58:34

What command can I execute to check the directories inside a folder and if the total size of the directory is smaller than 30MB, delete it? I played around with the find command trying to move files based in the size but it didn't work properly.

I was using (for 1mb):

find . -size +102400k -exec mv DIRECTORY

find . -size -102400k -exec mv DIRECTORY

If we're talking about directory size, I'm not sure find is going to help. du is going to have to be involved at some point.

Here's something I have written to find near directories under 30M:

du --max-depth 1 | awk -v q='"' '$1 < 30000000 && $2 != "." {sub(/^[0-9	 ]+/, "", $0); print q $0 q}'

You can then chain that into xargs rm -rf but I would test it very seriously before doing that. You might want to move the directories (with mv) instead of straight-up deleting them.
