Find files that contain filler (0x00)

My qbitorrent was set to preallocate files.



After a crash it lost a lot of torrents many of which were incomplete. (I purged it afterward, using deluge now)



I have a directory containing 1000s of folders and files in which I need to find the incomplete ones. I assume the filler used is 0x00, is there a simple command that would iterate over all files and echo the ones that contain 0x00's above some threshold?



After searching I found this but don't know how to complete it:



grep -P 'x00NNN' File





grep find search

grep -rlaP 'x004096' your_directory


Change 4096 to the actual length of a run of null bytes you're after.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
