Bash - Removing Linefeed character from a script

I have a script that I've largely finished except for one issue I just can't seem to crack removing a linefeed character before it gets passed to zbarimg. I've tried various things looked around online and can't seem to find anything to get rid of this pesky character. Any help would be greatly appreciated.

#!/bin/bashfolder=~/Publiccdate=$(date +"%Y-%m-%d-%H:%M")inotifywait -m -q -e create -r --format '%:e %w%f' $folder | while read file  do    ifile=$(ls -Art ~/Public | tail -n 1)    ifile2=$(echo $ifile | tr '\n''')    echo $ifile2 >> /tmp/latest.txt    zbarimg $ifile2 | pluma  done

Output of ls -alrt (last few lines)
