File::Compare(3p)Perl Programmers Reference GuidFile::Compare(3p)NAMEFile::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.
AUTHORFile::Compare was written by Nick Ing-Simmons. Its original
documentation was written by Chip Salzenberg.
