Anyway:
Code:

done

Not that it affects the command in any way, but yes, the "-1" is not required.
I generally prefer 1 liner to run on the prompt and most of the requests are for that.
But, I do like your approach too.

Doesthis solve your issue?
Or is it necessary it has to be done your way?
Are you sure you gave the quotes in the "&"?
Ok. First try this and see what comes out:
Code:
ls *track* | sed 's/.*\(track.*$\)/cp "&" \1/'

If that looks good then try this:
Code:
ls *track* | sed 's/.*\(track.*$\)/cp "&" \1/' | ksh

But if you are not looking for an one liner, then the codeby Reborg looks more simpler.
