Can the Finder resume a file copy

So, does it matter if the file is the same file?

ie: Let say there is a picture google.png

and you want it to copied into the same dir 4 times.

as an in that directory you would have google.png google 2.png google 3.png google 4.png?

If thats what you want:

for i in {1..4}
  do
     cp google.png "google$i.png"
  done

But if you want the "images" files to be different, and they are going to be gibrish files, but 10m in size exactly

you wanna do something like

for i in {1..5}
   do
      dd if=/dev/random of="yourfilename$i.test" bs=12428800 count=1
   done

This will make four files that are 10m in size filled with bunch of random characters.

Comment and let me know what you really want and I can go back and redo this.

It would help if you posted your script that fails so I can see what youre trying to do.

EDIT:

Changed the in device from /dev/zero to /dev/random to generate random file content.

The "washed out" items are basically just placeholders that the files were meant to be copied into. Those files aren't anything until the copy finishes and the real files are there. You can safely delete them and start over.

Step one, I would just reboot. This makes sure any copy operations are ended and you know it's safe to delete the placeholders once you've rebooted.

Sometimes Finder gets upset about you trying to delete its placeholders because it thinks they are still in use (busy). If this happens, open Terminal and use

sudo rm -rf /path/to/file/

Replace /path/to/file/ with the actual path, obviously.

That command will allow you to delete ANYTHING, even stuff your Mac needs to run, so make SURE you point it at the right files. They will be gone after this command runs, ignoring all warnings and restrictions. ...but that's fine for these placeholders; you just want them gone so you can try again.
