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]} ) RETURNFile::Compare::compare return 0 if the files are equal, 1 if the files are unequal, or -1 if an error was encountered.AUTHORFile::Compare was written by Nick Ing-Simmons. Its original documentation was written by Chip Salzenberg.
