NAME
	  cmp -	Compares two files

     SYNOPSIS
	  cmp [-l | -s]	file1 file2


	  The cmp command compares two files.

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

	  -s  Does not print data for differing	files; returns only an
	      exit value.


     DESCRIPTION
	  If file1 or file2 is specified as a -	(dash),	standard input
	  is used.  By default,	the cmp	command	prints no information
	  if the files are the same.  If the files differ, cmp prints
	  the byte and line number where the difference	occurred.  The
	  cmp command also specifies whether one file is an initial
	  subsequence of the other (that is, if	the cmp	command	reads
	  an End-of-File character in one file before finding any
	  differences).	 Normally, you use the cmp command to compare
	  nontext files	and the	diff command to	compare	text files.

	  Note that bytes and lines reported by	cmp are	numbered from
	  1.

     EXAMPLES
	   1.  To determine whether two	files are identical, enter:

	       cmp prog.o.bak prog.o



	       The preceding command compares the files	prog.o.bak and
	       prog.o.	If the files are identical, a message is not
	       displayed.  If the files	differ,	the location of	the
	       first difference	is displayed.  For instance:

	       prog.o.bak prog.o differ:  byte 5, line 1



	       If the message cmp: EOF on prog.o.bak is	displayed,
	       then the	first part of prog.o is	identical to
	       prog.o.bak, but there is	additional data	in prog.o.  If
	       the message cmp:	EOF on prog.o is displayed, it is
	       prog.o.bak that is the same as prog.o but also contains
	       addition	data.

	   2.  To display each pair of bytes that differ, enter:

	       cmp -l prog.o.bak prog.o



	       This compares the files and then	displays the byte
	       number (in decimal) and the differing bytes (in octal)
	       for each	difference.  For example, if the fifth byte is
	       octal 101 in prog.o.bak and 141 in prog.o, then the cmp
	       command displays:

	       5 101 141
	       .
	       .



     EXIT VALUES
	  Exit value 0 (zero) is returned for identical	files, 1 for
	  differing files, and 2 for an	inaccessible file or a missing
	  argument.
