In a subdirectory, how do I delete all files that are 0 bytes in size?

Question

I am used to listing and sorting the size of files as follows:

$ for entry in $(ls); do du -s "$entry"; done | sort -n

However, how does one delete all files of 0 bytes?

My terrible attempt would be to try an if conditional, but I don't know how to check the size. I would then pipe all results and remove these?

$ for entry in $(ls); if du -s "$entry" == 0 | rm "$entry"

don't parse the output of ls – Kusalananda May 10 '17 at 17:40 — Kusalananda, May 10 '17 at 17:40

You could use find:

find . -maxdepth 1 -type f -size 0 -delete

find * -prune -type f -size 0 -exec rm {} \; if you don't have -maxdepth – Fox May 10 '17 at 17:41

Updated my answer to add -type f, thanks @Fox – thiagowfx May 10 '17 at 17:52
Just FYI, I don't think maxdepth works with OS X – ShanZhengYang May 10 '17 at 18:05
@ShanZhengYang I don't know about newer OS X, but it works in 10.4.11 – Fox May 10 '17 at 19:43
