CMP(1)                      General Commands Manual                     CMP(1)



NAME
       cmp - compare two files

SYNOPSIS
       cmp [ -lLs ] file1 file2 [ offset1 [ offset2 ] ]

DESCRIPTION
       Cmp compares the two files and prints a message if the contents differ.

       The options are:

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

       -L     Print the line number of the first differing byte.

       -s     Print nothing for differing files, but set the exit status.

       If offsets are given, comparison starts at the designated byte position
       of the corresponding file.  Offsets that begin with 0x are hexadecimal;
       with 0, octal; with anything else, decimal.

DIAGNOSTICS
       If a file is inaccessible or missing, the exit status is If  the  files
       are  the  same,  the exit status is empty (true).  If they are the same
       except that one is longer than the other, the exit status is  Otherwise
       cmp  reports  the  position  of the first disagreeing byte and the exit
       status is
