Title pretty much nailed it, Im copying files to a flash drive and then doing some things to those files. Well I have noticed that after running the dd command the flash drive is still flashing and not all the files are on the device.
Does anyone know how to maybe run a simple loop (in script) to wait on the dd process to finish? I have been googling for about 2-3 hours now trying to figure it out and its beyond me if its even possible.
Thanks in advance!

Most likely you are seeing the operating system caching the writes. If you really want to make sure that everything is written to the flash drive so that it is safe to remove, it needs to be unmounted.
