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' (Note:Directories) and `-exec
rm -rf '{}' ';'' (Note:Single File).
