bytepad

Pads a file to a desired size with a specified padding byte

Usage

./bytepad -size=<new size of file> -data=<byte data to pad file with> <path to file>

Example

To pad file EVGA.GTX680.2048.120713.rom with FF's to 262144 bytes (256KiB):

./bytepad -size=262144 -data=0xFF ~/Downloads/EVGA.GTX680.2048.120713.rom

You can also omit -data in which 00's will be used for padding:

./bytepad -size=262144 ~/Downloads/EVGA.GTX680.2048.120713.rom
