change if-else loop to while-do

Hello friends,

i wrote a script which includes a couple of if-else loops but i have to change it to while-do loop as it is not allowed to use "break" in if-else loop in bash.

Code:

#!/bin/bash -x
NUM=`find . -name ufsdump_output1.txt | xargs egrep "End-of-tape detected"`
if [ "$NUM" = "" ]; then  echo "OK!"
elif [ "$NUM" = "End-of-tape detected" ]; then echo "NOT OK!"  exit 2
fi

i coudlnt conclude the script so i'd like to have your support pls:

Code:

while [ "$NUM" = "" ];
do echo "OK!"
else ......  ##what "elif" part corresponds to? in while-do loop?##

thanks by advanced
