1. grep -b is supposed to give me byte offsets into the file where the pattern occurs. however: sf root # egrep Exif -b /dev/hdb3 Binary file /dev/hdb3 matches no byte offsets. why? 2. how do i use grep to find a hex pattern, eg FFD9 (which marks the end of a jpeg file). I guess I have to escape it somehow, can anyone tell me? (sorry i feel i should know this one, but i don't) 3. how do i truncate a file to n bytes long? I thought there was a truncate command, but I may have the wrong name. -- Nick Rout <[EMAIL PROTECTED]>
