awk sed shell script

#!/bin/ksh

file='data.txt'
l=1
while read line
do
echo $line
awk '{sub(/^/, "/how could I paste a word in front of a line/");print}' data2.txt > ${line}.txt
((l+=1))
done < "${file}"

I have "data.txt" and "data2.txt" files.

data.txt includes 5 lines like that;

bu
bu1
bu2
bu3
bu4

I want to read each line one by one. For example when I get the first line "bu" I want to put it in front of all the lines in data2.txt file. And I want to get a file which name "bu.txt"

Second I will get "bu1" and put it in data2.txt at the beginning of each line. And I will get "bu2.txt".

...

How could I do that ?

Any suggestion would be welcome.

some suggestions
1) you do not need to use "sub" or gsub or even awk if you want to use the while loop. to "paste" something in front of a line, just echo it in front . eg echo "new word $line" .
2) to create new files, i am sure you know the > or >> operator. If not, read up the docs (my sig on bash)

Hi

I solved my problem on my own

awk -v line=$line '{sub(/^/, "/You can paste like this/"line"/");print}' data2.txt > ${line}.txt

here is the power of AWK again

If you want to understand the problem in detail use the link at the previous message.

Thanks to all
