Estimate file space usage
## After Help
Display values are in units of the first available SIZE from --block-size,
and the DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables.
Otherwise, units default to 1024 bytes (or 512 if POSIXLY_CORRECT is set).
SIZE is an integer and optional unit (example: 10M is 10*1024*1024).
Units are K, M, G, T, P, E, Z, Y (powers of 1024) or KB, MB,... (powers
of 1000).
PATTERN allows some advanced exclusions. For example, the following syntaxes
are supported:
? will match only one character
* will match zero or more characters
{a,b} will match a or b
