NAME
cmp - compare two files byte by byte SYNOPSIS
cmp [OPTION]... FILE1 [FILE2 [SKIP1 [SKIP2]]] DESCRIPTION
Compare two files byte by byte. -b --print-bytes Print differing bytes. -i SKIP --ignore-initial=SKIP Skip the first SKIP bytes of input. -i SKIP1:SKIP2 --ignore-initial=SKIP1:SKIP2 Skip the first SKIP1 bytes of FILE1 and the first SKIP2 bytes of FILE2. -l --verbose Output byte numbers and values of all differing bytes. -n LIMIT --bytes=LIMIT Compare at most LIMIT bytes. -s --quiet --silent Output nothing; yield exit status only. -v --version Output version info. --help Output this help. SKIP1 and SKIP2 are the number of bytes to skip in each file. 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. AUTHOR
