Still syntax errors.

could you please try running the script on your machine.

myfile.txt has following

1
2
3
4
5
6

lorcan:

#!/usr/bin/sh
read file
#exec 3<&0
exec 0<$file
while read line
do
   if [[ $count -eq 4 ]]
   then
   BOUND=$line
   break
   fi
   count=`expr $count + 1`
done
#exec 0<&3
echo $BOUND

Intialize count to zero before while loop
