Hi,
Thanks for the below input.
However if we are using Join command, the position of the element in the matching file could not be retrived as similar elements are already grouped together.
I assume that the join results would be pipe into a new output file.
So far I have:-
cat a.txt| while read LINE
do
char=`echo "${LINE}"| awk '{print $2}'`
echo $char
cat b.txt| awk '{
#grep -n $char b.txt| tr ":" " "|awk '{print $1}'
done
However, I am stuck in how to retrieve the first field of b.txt.
Next, I am stuck in getting the current line found in b.txt
Please advise.Thanks.
