Without a sample of your data, this sounds like you
want to use join.

Given you have the 3 files X, Y and Z with the following content:

  $ cat X
  1 x1
  2 x2
  3 x3

  $ cat Y
  1 y1
  2 y2
  3 y3

  $ cat Z
  1 z1
  2 z2
  3 z3

If you don't have the line numbers, then you can easily
create them with e.g. "cat -n X".

Then you can join X and Y (column 1 will be the key),
and join the result (indicated by stdin "-") with Z:

  $ join X Y | join - Z
  1 x1 y1 z1
  2 x2 y2 z2
  3 x3 y3 z3

Have a nice day,
Berny

Rather than attempting to describe the problem, giving us an actual
sample of three files, each containing three or so lines, as well as the
desired output you want, would go a lot further in explaining the
problem you really want solved.  I will attempt to describe a setup that
I think matches the wording you gave.  I created three files:

$ cat one
1
2
3
$ cat two
a
b
c
$ cat three
x
y
z

Then I can use something like this to merge those three files into a
single listing with three columns, one entry from each file:

$ join <(join <(cat -n one) <(cat -n two)) <(cat -n three) |\
   sed 's/^[0-9]* *//'
1 a x
2 b y
3 c z

There's probably other ways of doing it, as well.

At any rate, your request is more of a usage question, and not an actual
bug report.  To avoid polluting the bug tracker with something that
needs no further action in coreutils, I have marked this as not a bug.
But you should still feel free to reply if you have further comments, or
can provide more details about the real problem you are trying to solve.

Unfortunately, it is now posted to a public archive, and this disclaimer
is rendered unenforceable.  For better netiquette, you may want to
consider posting from a private account, rather than one where your
employer tacks on lame legalese.

Actually,
pr -m -t -s' ' one two three
seems to be easier to me for this case...

Awesome trick - I would have never thought of pr.  Should we mention
pr(1) in the SEE ALSO of 'man join'?

Maybe, might be useful for someone - though I think this is more
suitable for info documentation example/link...
