Shell Programming and Scripting

I created a bash script that gets a file formats it, sends an email to the user(s), however, for whatever reason, it will send an email per line with all of the lines in it, so essentially the user will get 10 duplicate emails with the same 10 results. I've modified the script to put the results of each user into a file with the user's email address, but I'm not sure how to limit the script to send only one email on however many lines there is for each user. Please see what I have, I'd appreciate any suggestions.

Code:

TMPDIR=TEMP
    mkdir "${TMPDIR}" || { echo "failed to create temporary dir ${TMPDIR}";exit 1;}
    printf "${EMAIL%%@*},\n\n$MESSAGE\n\n$DETAIL"  >>"${TMPDIR}/${EMAIL}"
    
    for FILE in "${TMPDIR}"/*; do  
    mailx -s "TEST EMAIL" -r test@admin.com "${FILE##*/}" <"${FILE}"
    rm -r "${TMPDIR}"
    done
    DETAIL=''
    done

The 2nd done indicates you have two nested loops?
Either have them one after the other, or more elegantly without a TMPDIR

Code:

...loop...
do
  printf "${EMAIL%%@*},\n\n$MESSAGE\n\n${DETAIL}\n" |
    mailx -s "TEST EMAIL" -r test@admin.com "${EMAIL}"
done

Thanks MadeinGermany! I tried the same thing you recommended, but it's doing the same thing. Not sure what I'm doing wrong with loop.

Is there any way I can add some function that will only send out one email, after the content is stored into a file?
