Shell variables are not expanded when they appear in a command line between single quotes. Try changing the single quotes in the sed command first argument:
Code:
cnt=`wc -l $CONTROLFILE | awk '{print $1}'`
sed '2s/^/$cnt/' $CONTROLFILE

to double quotes:
Code:
cnt=`wc -l $CONTROLFILE | awk '{print $1}'`
sed "2s/^/$cnt/" $CONTROLFILE
