I'm running a loop like this:



for ip in 10.0.0.1 10.0.0.2 10.0.0.3; do traceroute $ip; done


I want to be able to kill the current traceroute when it gets boring (and before its 30-hop max), and move on to the next one. But when I press Ctrl+c, it kills the whole for loop.



I guess what I need is either a way to end the current traceroute, or to send the loop a continue.



This question and this one are doing a similar thing, but in more complicated situations. Is there a reasonable way to do this when just running stuff from the prompt?




bash

          Use trap:

          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...
