cmp - compare two files
cmp [ -l ] [ -s ] file1 file2
The two files are compared. (If file1 is `-', the standard
input is used.) Under default options, cmp makes no comment
if the files are the same; if they differ, it announces the
byte and line number at which the difference occurred. If
one file is an initial subsequence of the other, that fact
is noted. Moreover, return code 0 is yielded for identical
files, 1 for different files, and 2 for an inaccessible or
-l Print the byte number (decimal) and the differing
bytes (octal) for each difference.
-s Print nothing for differing files; return codes only.
