bash script on copying file that is modified very recent

I need a script to get the latest updated file and copy over to remote servers. Also, the script should terminate once run itself.

I have tried with While loop, it does copy but I am unable to stop the scripts once it completes its job. or I missed something not known to me. 

#!/bin/bash
FILE="/opt/testdir/file.txt"
LATEST=$(ls -Art | tail -n 1)
while [ $LATEST != $FILE ] 
do 
rsync -avz $LATEST 192.168.20.20:/opt/testdir/.
done

i) file should copy to remote server and whenever script runs it copies over to remote server same file overwrite.

Maybe with using inotify tools

# monitor current directory ./
# and get dir/file paths on these file-system events:
# - close_write (file written and closed)
# - create (file created)
# - moved_to (file moved to here)

inotifywait \
  --quiet \
  --monitor \
  --event close_write \
  --event create \
  --event moved_to \
  --format '%w%f' \
  ./ \
  | {
    # loop through all files
    # as inotifywait may return multiple files (one per line)
    while read -r LATEST; do
      rsync \
        --archive \
        --compress \
        --verbose \
        "${LATEST}" \
        192.168.20.20:/opt/testdir/.
    done
  }
