Not only is ls unnecessary, but it will break the script if there is whitespace in any of the filenames. It should be:

Code:
for i in *.txt

Quote:
Code:
do
	val=`cat $i | tail -1 | awk '{print $1}'`


The OP was not clear whether the line in question was the last of the file; that only works if it is.

Also, there is no need for cat or tail:
Code:
val=`awk 'END {print $1}' "$i"`

Quote:
Code:
	nawk -v val="$val" '{
		if(index($0,"STOP")!=0)
			print $0"  "val
		else
			print
	}' $i
done
