So, here's the plain detailed explanation I would have liked to receive instead of all the nonsense I got.

Let's suppose we have a Linux system and a FreeDOS boot floppy that we want to make available on the net for people who want to flash their BIOS with an .exe file, the only kind provided by the motherboard manufacturer.

On this floppy disk (fd), we have files such as command.com for
instance.

You *are* joking, I hope? There's no such thing as command.com on
any *nix system.

"we have (...) a FreeDOS boot floppy" Try to read before getting so upset.

The Linux cp command could copy them but, unfortunately, since both
OS differ in their conception, the files might slightly differ.


No, the cp command will copy them byte for byte. They will be
identical.

Here, you're right. I thought there were cases where the cp command would not copy files exactly from on OS to another, but I just checked the man page and you are right about this.
