How can I append the same byte to a file a specified number of times?

I have the following code:

yes "$(echo -e "\xff")" | head -n 10 > SomeFile.bin

Which writes 10 times 0xFF and 0x0A (newline) to SomeFile.bin. But my objective is to fill the file with FF.

Is there a way to print only consecutive 0xFF values instead? Without adding a newline every time?

>Solution :

Here is one way:

printf '\xFF%.s' {1..10} >SomeFile.bin
