cmp(1)                                                     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 flag options, cmp makes no
          comment if the files are the same; if they differ, it an-
          nounces the byte and line number at which the difference oc-
          curred.  If one file is an subset of the other, that fact is
          noted.

     FLAG OPTIONS
          The following flag options are interpreted by cmp:

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

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

     EXAMPLES
               cmp alpha beta

          will report if the files are different and at what point
          they differ, such as:

               alpha beta differ: char 33, line 2

     FILES
          /bin/cmp

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