in reply to do until loops

I'm trying to do a simple copy command that will overwrite a file a specific number of times(i.e 10 times and then terminate) using the do until command. Can anyone give me some advise on this.

    couldnt you do something like this
    $value=0; do{ "copy command" $value=$value+1; } until($value==9);
