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. AAUUTTHHOORR Written by Torbjorn Granlund and David MacKenzie.
