4 Invalid terminfo capability.
cmp [–blsxB] file1 file2 [seek1[seek2]]
cmp compares two files. If either filename is –, cmp reads the standard input
(stdin) for that file. By default, cmp begins the comparison with the first byte of
each file. If you specify seek1 and/or seek2, cmp uses it as a byte offset into file1
or file2 (respectively), and comparison begins at that offset instead of at the
beginning of the files. The comparison continues (1 byte at a time) until a difference
is found, at which point the comparison ends and cmp displays the byte and line
number where the difference occurred. cmp numbers bytes and lines beginning
with 1.
–b Compares single blocks at a time. Normally, cmp reads large buffers of
data into memory for comparison.
–l Causes the comparison and display to continue to the end; however, cmp
attempts no resynchronization. cmp displays the byte number (in decimal)
and the differing bytes (in octal) for each difference found.
