NAME

6       File::Compare - Compare files or filehandles
7

SYNOPSIS

9               use File::Compare;
10
11               if (compare("file1","file2") == 0) {
12                   print "They're equal\n";
13               }
14

DESCRIPTION

16       The File::Compare::compare function compares the contents of two
17       sources, each of which can be a file or a file handle.  It is exported
18       from File::Compare by default.
19
20       File::Compare::cmp is a synonym for File::Compare::compare.  It is
21       exported from File::Compare only by request.
22
23       File::Compare::compare_text does a line by line comparison of the two
24       files. It stops as soon as a difference is detected. compare_text()
25       accepts an optional third argument: This must be a CODE reference to a
26       line comparison function, which returns 0 when both lines are
27       considered equal. For example:
28
29           compare_text($file1, $file2)
30
31       is basically equivalent to
32
33           compare_text($file1, $file2, sub {$_[0] ne $_[1]} )
34

RETURN

36       File::Compare::compare and its sibling functions return 0 if the files
37       are equal, 1 if the files are unequal, or -1 if an error was
38       encountered.
