CMP(1)                      General Commands Manual                     CMP(1)



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  subsequence
       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 inaccessible or missing argument.
