the beginning of each file (zero by default).
Mandatory arguments to long options are mandatory for short options

output byte numbers and differing byte values
compare at most LIMIT bytes
-s, --quiet, --silent
suppress all normal output
--help display this help and exit
output version information and exit
SKIP values may be followed by the following multiplicative suffixes:
kB 1000, K 1024, MB 1,000,000, M 1,048,576, GB 1,000,000,000, G
1,073,741,824, and so on for T, P, E, Z, Y.
