Dear sir, I cannot thank you enough for your help.
I have what I have been looking for....thanks to you.

Just as a summary, this is the complete example:

Code:

gile.sh

Code:

#!/bin/bash
while read lineA
    do while read lineB
        do echo $lineA" -delimiter- "$lineB
        done < fsecond.txt
done < ffirst.txt

Code:

The OUTPUT:
> ./gile.sh
A -delimiter- 1
A -delimiter- 2
A -delimiter- 3
A -delimiter- 4
A -delimiter- 5
A -delimiter- 6
A -delimiter- 7
A -delimiter- 8
A -delimiter- 9
A -delimiter- 10
A -delimiter- 11
B -delimiter- 1
B -delimiter- 2
B -delimiter- 3
B -delimiter- 4
B -delimiter- 5
B -delimiter- 6
B -delimiter- 7
B -delimiter- 8
B -delimiter- 9
B -delimiter- 10
B -delimiter- 11
C -delimiter- 1
C -delimiter- 2
C -delimiter- 3
C -delimiter- 4
C -delimiter- 5
C -delimiter- 6
C -delimiter- 7
C -delimiter- 8
C -delimiter- 9
C -delimiter- 10
C -delimiter- 11
D -delimiter- 1
D -delimiter- 2
D -delimiter- 3
D -delimiter- 4
D -delimiter- 5
D -delimiter- 6
D -delimiter- 7
D -delimiter- 8
D -delimiter- 9
D -delimiter- 10
D -delimiter- 11
E -delimiter- 1
E -delimiter- 2
E -delimiter- 3
E -delimiter- 4
E -delimiter- 5
E -delimiter- 6
E -delimiter- 7
E -delimiter- 8
E -delimiter- 9
E -delimiter- 10
E -delimiter- 11
F -delimiter- 1
F -delimiter- 2
F -delimiter- 3
F -delimiter- 4
F -delimiter- 5
F -delimiter- 6
F -delimiter- 7
F -delimiter- 8
F -delimiter- 9
F -delimiter- 10
F -delimiter- 11

Note: I have updated first file with F and second file with 11....to see how it works.

For the real purpose of the script, first file I am going to use is about 5000 lines long, and second is 3500 lines long....just to update you with the real info.

Dear RudiC, if you think that this code can run more smoothly, I kindly ask you to offer such solution.

Best regards...and thank you very much
