NAME
       cmp - compare two files

SYNOPSIS
       cmp [ -l ] [ -s ] file1 file2

DESCRIPTION
       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 subse-
       quence of the other, that fact is noted.

       Options:

       -l    Print the byte number (decimal) and the differing bytes (octal) for each difference.

       -s    Print nothing for differing files; return codes only.

SEE ALSO
       diff(1), comm(1)

DIAGNOSTICS
       Exit code 0 is returned for identical files, 1 for different files, and 2 for an  inacces-
       sible or missing argument.
