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.
