Answer 1

You could do it in two steps with cat -n followed by join. (cat -n reproduces your file with line numbers at the start of each line. join joins the two files on the line numbers.)

$ echo "A" > test_a
$ echo "B" >> test_a
$ echo "X" > test_b
$ echo "Y" >> test_b
$ cat -n test_a > test_a.numbered
$ cat -n test_b > test_b.numbered
$ join -o 1.2 -o 2.2 test_a.numbered test_b.numbered
A X
B Y
