What a gross mess, blazar. Anything other than something like the following is not worth your time:

use File::Copy;
$basedir='/path/to/files';
$foo = $_;
$foo =~ s#/#slash#g;
$foo =~ s#->#arrow#g;
$fubar = "$basedir/$_";
copy($fubar, "$basedir/$foo");
$scp->put("$basedir/$foo");
system('rm', "$basedir/$foo") 
 && die "Can't remove $foo:$!\n";

with appropriate my's and stricts as appropriate.
