Given you're looking at trying to determine whether a directory has files you could either do it the way you've initially written up your code or use 'find' The possible 'issue' with the original 'cp *' is if there was a boatload of files in the directory, you could get a shell expansion error. Probably very unlikely. One way to handle the corner case is to use find - see the execdir/exec option.
