not sure what you mean by '2 lines' or '3 lines', but what have you tried to so?

hi thanks for the reply,

i missed something during my first post since it was 2 strings only...like:

file1:
a 1
b 2

file2:
1 something
2 nothing

output to:
a 1 something
b 2 nothing

which is diff. from the post above due to file 1 uses 3 strings in a line

Once again, how's that different from this thread?
And if there's any difference, what have you tried so far modifying the original solution?
