commands

If I use Dos command "copy" to concatenate two files: copy a1.txt + a2.txt a.txt

I will have something like the following in stdout: C:\a1.txt C:\a2.txt 1 file(s) copied.

I do not want to have anything written in stdout, I mean, I just want to have 'a.txt' without those 3 lines written in stdout. Is there any way to do so? the reason is, I need speed and I know that any IO takes time.

Thanks, Shadi.
