How to wait for a for loop in a bash script?

Question

bash

Wrote a script for Nautilus that changes the encoding of selected files.
I want to display a notification after the end of the operation, but as far as I know, the loop is executed in a separate thread and the notification appears before it completes.
How to wait until the end of the loop?

#!/bin/bash

FROM=cp1251
TO=utf-8
ICONV="iconv -f $FROM -t $TO"

for file in [email protected]
do
  if [ -f $file ]; then
    tmpf="/tmp/${file}.bak"
    cp ${file} ${tmpf}
    $ICONV < ${tmpf} > ${file}
    rm ${tmpf}
  fi
done

# /usr/share/icons/hicolor/48x48/apps/
# Параметр -i  - имя иконки без расширения
notify-send -i ktip "Операция завершена!" "Кодировка файлов изменена на UTF-8"
