Size

Test: -size n[bckw]

True if the file uses n units of space, rounding up. The units are 512-byte blocks by default, but they can be changed by adding a one-character suffix to n:

b

512-byte blocks

c

bytes

k

kilobytes (1024 bytes)

w

2-byte words

The size does not count indirect blocks, but it does count blocks in sparse files that are not actually allocated.

Test: -empty

True if the file is empty and is either a regular file or a directory. This might make it a good candidate for deletion. This test is useful with `-depth' (see section Directories) and `-exec rm -rf '{}' ';'' (see section Single File).
