16 cfa37a7b 2004-04-10 devnull .SH DESCRIPTION
17 cfa37a7b 2004-04-10 devnull The two files are
18 cfa37a7b 2004-04-10 devnull compared.
19 cfa37a7b 2004-04-10 devnull A diagnostic results if the contents differ, otherwise
20 cfa37a7b 2004-04-10 devnull there is no output.
21 cfa37a7b 2004-04-10 devnull .PP
22 cfa37a7b 2004-04-10 devnull The options are:
23 cfa37a7b 2004-04-10 devnull .TP
24 cfa37a7b 2004-04-10 devnull .B l
25 cfa37a7b 2004-04-10 devnull Print the byte number (decimal) and the
26 cfa37a7b 2004-04-10 devnull differing bytes (hexadecimal) for each difference.
27 cfa37a7b 2004-04-10 devnull .TP
28 cfa37a7b 2004-04-10 devnull .B s
29 cfa37a7b 2004-04-10 devnull Print nothing for differing files,
30 cfa37a7b 2004-04-10 devnull but set the exit status.
31 cfa37a7b 2004-04-10 devnull .TP
32 cfa37a7b 2004-04-10 devnull .B L
33 cfa37a7b 2004-04-10 devnull Print the line number of the first differing byte.
34 cfa37a7b 2004-04-10 devnull .PP
35 cfa37a7b 2004-04-10 devnull If offsets are given,
36 cfa37a7b 2004-04-10 devnull comparison starts at the designated byte position
37 cfa37a7b 2004-04-10 devnull of the corresponding file.
38 cfa37a7b 2004-04-10 devnull Offsets that begin with
39 cfa37a7b 2004-04-10 devnull .B 0x
40 cfa37a7b 2004-04-10 devnull are hexadecimal;
41 cfa37a7b 2004-04-10 devnull with
42 cfa37a7b 2004-04-10 devnull .BR 0 ,
43 cfa37a7b 2004-04-10 devnull octal; with anything else, decimal.

49 cfa37a7b 2004-04-10 devnull If a file is inaccessible or missing, the exit status is

51 cfa37a7b 2004-04-10 devnull If the files are the same, the exit status is empty (true).
52 cfa37a7b 2004-04-10 devnull If they are the same except that one is longer than the other, the exit status is

55 cfa37a7b 2004-04-10 devnull .I cmp
56 cfa37a7b 2004-04-10 devnull reports the position of the first disagreeing byte and the exit status is
