I am using BASH.

Code:

$ join file1 file2 -a 1 -a 2
AAAA 23 45 34 54
AAAB 44 56
AAAC 34 65
AAAD 34 87
AAAE 34 56

AAAD    34 87
AAAE 34 56

I didn't think either of these matched the desired output.

I did small mistake there file2 consider as first, it should be second. And as i don't worry too much about spacings. Smilie

Now output looks like(This also not looks like OP's desired output Smilie

considering spacings)

Code:

AAAA 23 45 34 54
AAAE    34 56
AAAB 44 56
AAAC 34 65
AAAD 34 87

But if you have removed spacings part the output is what OP want.

Yes your script gives exact output as OP want.
You always comes with perfect solution.. Smilie

Thanks
