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



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.
