Here's a really crude thing I threw together just now that worked for me. Some variation on this, which just gets a list of files and checksums with "ssh", might help.
Replace HOST1 and HOST2 with hostnames that will work on an "ssh" command. Meaning, short names if that works or fully qualified domain names. It just needs to get you to the server the script doesn't use that info afterwards.
And replace PATH-TO-DIRECTORY with the top of the directory tree you want to compare.
I tried just doing "-exec sum {} \;" in the "find" but it doesn't print the filename on the systems I'm using. That's why there's a shell script consuming the output from find and running "sum".

Hey Unix Gurus,
I'm having trouble in copying a file on 5 different servers, first how can you do it locally (i.e without the need to ssh to the server you want to copy the file) and if you need to ssh how do u run a command within that server. Please see my code below(it doesn't work somehow).... (10 Replies)

Algorithm::DiffOld(3) User Contributed Perl Documentation Algorithm::DiffOld(3)NAME
Algorithm::DiffOld - Compute `intelligent' differences between two files / lists but use the old (<=0.59) interface.
NOTE
This has been provided as part of the Algorithm::Diff package by Ned Konz. This particular module is ONLY for people who HAVE to have the
old interface, which uses a comparison function rather than a key generating function.
Because each of the lines in one array have to be compared with each of the lines in the other array, this does M*N comparisions. This can
be very slow. I clocked it at taking 18 times as long as the stock version of Algorithm::Diff for a 4000-line file. It will get worse
quadratically as array sizes increase.
SYNOPSIS
use Algorithm::DiffOld qw(diff LCS traverse_sequences);
@lcs = LCS( @seq1, @seq2, $comparison_function );
$lcsref = LCS( @seq1, @seq2, $comparison_function );
@diffs = diff( @seq1, @seq2, $comparison_function );
traverse_sequences( @seq1, @seq2,
{ MATCH => $callback,
DISCARD_A => $callback,
DISCARD_B => $callback,
},
$comparison_function );
COMPARISON FUNCTIONS
Each of the main routines should be passed a comparison function. If you aren't passing one in, use Algorithm::Diff instead.
These functions should return a true value when two items should compare as equal.
For instance,
@lcs = LCS( @seq1, @seq2, sub { my ($a, $b) = @_; $a eq $b } );
but if that is all you're doing with your comparison function, just use Algorithm::Diff and let it do this (this is its default).
Or:
sub someFunkyComparisonFunction
{
my ($a, $b) = @_;
$a =~ m{$b};
}
@diffs = diff( @lines, @patterns, &someFunkyComparisonFunction );
which would allow you to diff an array @lines which consists of text lines with an array @patterns which consists of regular expressions.
This is actually the reason I wrote this version -- there is no way to do this with a key generation function as in the stock
Algorithm::Diff.
