The problem is that the very last read statement isn't working. I've read all about how stdin is redirected and can't be leveraged by read until the program is complete, however I don't see any solutions on any fixes that actually work.

The problem is that the very last read statement isn't taking input from the user. I will get prompted with "[rescan]/exit: " and I have the ability to type, but when I press it just asks for input yet again without the "[rescan]/exit: " prompt. There are no errors whatsoever. I have to CTRL-C out of the script to terminate it because it gets stuck (I'm assuming) on the last read statement. I've read all about how stdin is redirected and can't be leveraged by read until the program is complete, however my while loop is complete and none of the solutions or fixes seem to circumvent my problem.

stdbuf -oL echo "list media" | bconsole | {

    while IFS= read -r line
    do
            line=$(echo ${line^^})
    done

}

read -p "[rescan]/exit: " userResponse

I've cut out a lot of the code in order to just narrow down on the problem I have. bconsole is a binary executable that I'm calling and the list media command does a dump of data to the stdout that I'm parsing with awk line-by-line.
