CMP(1)                  COMMAND REFERENCE                  CMP(1)



NAME
     cmp - compare two files

SYNOPSIS
     cmp [ -l ] [ -s ] filename1 filename2

DESCRIPTION
     The two files are compared.  (If filename1 or filename2 is a
     dash (-), the standard input is used.) When no options are
     specified, 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.

EXAMPLES
     The following compares a local version of echo with the
     version in /bin:



          cmp echo /bin/echo


RETURN VALUE
     [NO_ERRS]      Files are identical.

     [1]            Files are different

     [USAGE]        Incorrect command line syntax. Execution
                    terminated.

     [P_ERR]        A system error occurred. Execution
                    terminated.  See intro(2) for more
                    information on system errors.

CAVEATS
     Use of both option flags is identical to a call with no
     options.
