a=`wc -c filename1 | nawk '{print $1}` b=`wc -c filename2 | nawk '{print $1}'`
if [[ $a -eq $b ]]; then
echo "File sizes match."
else
echo "File sizes differ! "

Or maybe more like

Code:
set -- `ls -l "$file"`
size=$5
while true; do
  sleep 60
  set -- `ls -l "$file"`
  case $5 in $size) break;; esac
  size=$5
done

This will loop until the size of the file stays the same for 60 seconds. (You will need to set the variable file to the name of the file you want to monitor, of course.)
