Compare two files byte by byte.
The optional SKIP1 and SKIP2 specify the number of bytes to skip at the
beginning of each file (zero by default).
Mandatory arguments to long options are mandatory for short options
too.
--bb, ----pprriinntt--bbyytteess
print differing bytes
--ii, ----iiggnnoorree--iinniittiiaall=_S_K_I_P
skip first SKIP bytes of both inputs
--ii, ----iiggnnoorree--iinniittiiaall=_S_K_I_P_1:SKIP2
skip first SKIP1 bytes of FILE1 and first SKIP2 bytes of FILE2
--ll, ----vveerrbboossee
output byte numbers and differing byte values
--nn, ----bbyytteess=_L_I_M_I_T
compare at most LIMIT bytes
--ss, ----qquuiieett, ----ssiilleenntt
suppress all normal output
----hheellpp display this help and exit
--vv, ----vveerrssiioonn
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.
If a FILE is '-' or missing, read standard input. Exit status is 0 if
inputs are the same, 1 if different, 2 if trouble.
