File::Compare(3)       Perl Programmers	Reference Guide	      File::Compare(3)

NAME
       File::Compare - Compare files or	filehandles

SYNOPSIS
	       use File::Compare;

	       if (compare("file1","file2") == 0) {
		   print "They're equal\n";
	       }

DESCRIPTION
       The File::Compare::compare function compares the	contents of two
       sources,	each of	which can be a file or a file handle.  It is exported
       from File::Compare by default.

       File::Compare::cmp is a synonym for File::Compare::compare.  It is
       exported	from File::Compare only	by request.

       File::Compare::compare_text does	a line by line comparison of the two
       files. It stops as soon as a difference is detected. compare_text()
       accepts an optional third argument: This	must be	a CODE reference to a
       line comparison function, which returns 0 when both lines are
       considered equal. For example:

	   compare_text($file1,	$file2)

       is basically equivalent to

	   compare_text($file1,	$file2,	sub {$_[0] ne $_[1]} )

RETURN
       File::Compare::compare and its sibling functions	return 0 if the	files
       are equal, 1 if the files are unequal, or -1 if an error	was
       encountered.

AUTHOR
       File::Compare was written by Nick Ing-Simmons.  Its original
       documentation was written by Chip Salzenberg.
