Quite correct and thank you TB0ne, as well as sundialsvcs for noting this, as well as noting that techchamp had advertised in one of their posts.

techchamp has been contacted about this infraction of LQ rules.

Also to note is that the OP may not understand the solution, or may find that the solution is not correct or ideal for what they want or need and then have follow-up questions. Per TB0ne's and sundialsvcs' points, the OP hasn't learned, while it may or may not help them to pass one technical question, they may not understand the answer at all. Therefore techchamp, your actions are nearly pointless.

That "answer" is also pretty poorly done. There are a lot of mistakes and faux pas in it, despite being all on one line. If it produces the correct output, it might get minimal points, but only based on the output not how the output was generated.

Although you have a one-line answer, is it the best answer?
Its got no documentation and its quite likely going to be hard hard to amend it for a similar problem...

Anyway the OP was supposed to be using 'cut' so I think he will get no marks for using 'awk' etc.

It's not even a good answer let alone the best.
I don't want to break any rules, so I'll simply hint that you can do it all with a single 'join' command(*) and suggest you go read the manpage. Pay particular attention to the -t and -o options.


(*) Well, ok, if the input is not pre-sorted you'll probably also want 'sort'.
