I would change the approach from your script (sending a shell command loop to the remote side) to a three-step approach:

  1. Get the list of all remote files
  2. Munge the list in Perl
  3. Send a list of mv -i commands to the remote side

Using the three steps makes it much, much easier to review the list of commands before they are executed.

The relevant parts of the script would be:

# Get list of remote files
my @remote_files= qx(ssh $uid $h 'find $dirname');

# Munge filenames to commands:
my @commands= map { sprintf "mv -i '%s' '%s.bak'",
                              quotemeta($_), quotemeta($_)
                  } @remote_files;

[download]
# Send list of commands to the remote side:
# First, a dry-run instead of actually doing that:
my $remote= \*STDOUT;
# Use this to actually do the remote execution:
#open $remote, "| ssh -q -l $uid $h";
print { $remote } join "\n", @commands;
