Am nächsten dran ist cmp, aber das hat addr in decimal und data in octal!

dem läßt sich abhelfen:

Code: Alles auswählen

Fbindiff ()
{
	[[ ! $2 || ! -f $1 || ! -f $2 ]] && 

echo	"\n\t $FUNCNAME file1 file2 # dos fc-like binary diff!\n" && return

	cmp -l "$1" "$2" | perl -ne'
		if (/\s*(\d+)\s+(\d+)\s+(?:\S+\s+)?(\d+).*/) {
			$adr = $1-1; $old = oct($2); $new = oct($3);

			printf "%08X: %02X %02X\n", $adr, $old, $new;
		}'
}

 $ Fbindiff ucx-2.2.1.4.org ucx-2.2.1.4
