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.
