     cmp -- compare two	files

     cmp [-l | -s | -x]	[-hz] file1 file2 [skip1 [skip2]]

     The cmp utility compares two files	of any type and	writes the results to
     the standard output.  By default, cmp is silent if	the files are the
     same; if they differ, the byte and	line number at which the first differ-
     ence occurred is reported.

     Bytes and lines are numbered beginning with one.

     The following options are available:

     -h	   Don't follow	symbolic links.

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

     -s	   Print nothing for differing files; return exit status only.

     -x	   Like	-l but prints in hexadecimal and using zero as index for the
	   first byte in the files.

     -z	   For regular files compare file sizes	first, and fail	the comparison
	   if they are not equal.

     The optional arguments skip1 and skip2 are	the byte offsets from the
     beginning of file1	and file2, respectively, where the comparison will
     begin.  The offset	is decimal by default, but may be expressed as a hexa-
     decimal or	octal value by preceding it with a leading ``0x'' or ``0''.

     The cmp utility exits with	one of the following values:

     0	   The files are identical.

     1	   The files are different; this includes the case where one file is
	   identical to	the first part of the other.  In the latter case, if
	   the -s option has not been specified, cmp writes to standard	error
	   that	EOF was	reached	in the shorter file (before any	differences
	   were	found).

     >1	   An error occurred.

     diff(1), diff3(1)

     The cmp utility is	expected to be IEEE Std	1003.2 (``POSIX.2'') compati-

     A cmp command appeared in Version 1 AT&T UNIX.
