CentOS - Dec 2009 - Inquiry:How to compare two files but not in line-by-line basis?

Dear All
Can you please do me favor and let me know how can I compare two files but
not in line-by-line basis on my CentOS server ? I mean say row#1 in file1
has the same data as say row#5 in file2 , but the comm compares them in
line-by-line basis that is not intended . It seems that the diff cannot do
the job as well .
Thank you in advance

This'll show you which lines are common to both files, and for the 
ones that aren't which file they're in.

perl -MData::Dumper -le 'while(<>) {chomp; push
@{$s->{"$_"}},
$ARGV}; END{ print Dumper($s) }' file1 file2

... someone will be along shortly with a more elegant method.

diff -y ?

Thank you very much for your reply . This code actually solved my problem
and returned exact matches between the two files (irrespective of their
location in the files) . As I understood , it will list each data showing to
which file it belongs (or it is common to both files) . It is really what I
wanted .
Sincerely Yours

(( do not top-post ))

You could do the same by first sorting the two files, and then use
"comm".

Diff should resync after showing the some lines have been inserted.  If it shows
that no lines match when you think that some do, it may mean the files have 
different line endings.  Was one created under windows or transferred in a way 
that could change them?
