done 3<&0 < ${CWD}/out.txt


Code:
if [[ "$file" =~ "test.tar" ]] || [[ "$file" =~ "wow.tar" ]]
then
        continue
fi

Thank you; I will try these out tonight and let you know if they work realtime.

Another approach is to use a for loop instead:-
Code:
for file in data/*
do
        [[ "$file" =~ "test.tar" ]] && continue;

        read -p "Where do you want to copy ${file} to? enter absolute path: " cp_path

        echo "cp -R $file ${cp_path}/"
done

The files may not be in the data folder instead in its sub-directories.

Can you please confirm if replacing the find with for will still work as you suggested ?

rmm

RMM(1)                                                               [nmh-1.5]                                                              RMM(1)

NAME

       rmm - remove messages

SYNOPSIS

       rmm [+folder] [msgs] [-unlink | -nounlink] [-version] [-help]

DESCRIPTION

       By  default,  rmm  will remove the specified messages by renaming each of the message files with a site-dependent prefix (usually a comma).
       Such files will then need to be removed in some manner after a certain amount of time.  Many sites arrange for cron to remove  these  files
       once a day, so check with your system administrator.

       Alternately,  if  you  wish  for  rmm to really remove the files representing these messages, you can use the -unlink switch.  But messages
       removed by this method cannot be later recovered.

       If you prefer a more sophisticated method of `removing' messages, you can define the rmmproc profile component.  For example, you can add a
       profile component such as

            rmmproc:  /home/foouser/bin/rmm_msgs

       then instead of simply renaming the message file, rmm will call the named program or script to handle the files that represent the messages
       to be deleted.

       Some users of csh prefer the following:

            alias rmm 'refile +d'

       where folder `+d' is a folder for deleted messages, and

            alias mexp 'rm `mhpath +d all`'

       is used to "expunge" deleted messages.

       The current message is not changed by rmm, so a next
        will advance to the next message in the folder as expected.

FILES

       $HOME/.mh_profile          The user profile

PROFILE COMPONENTS

       Path:                To determine the user's nmh directory
       Current-Folder:      To find the default current folder
       rmmproc:             Program to delete the message

SEE ALSO

       refile(1), rmf(1)

DEFAULTS

       `+folder' defaults to the current folder
       `msgs' defaults to cur
       `-nounlink'

CONTEXT

       If a folder is given, it will become the current folder.

BUGS

       Since refile uses your rmmproc to delete the message, the rmmproc must NOT call refile without specifying -normmproc, or you will create an
       infinte loop.
