I'm trying to run a command that access a local switch CLI and runs a simple 'show config'. The script logs in, but then does nothing. I suspect it's because once logged in to the sub-terminal, the commands can't be interpreted. Any ideas?



$a1 = "show config"

exec cli

sleep 2

exec $a1
exec exit



bash

    Could you clarify "that access a local switch CLI"? is it about a network switch? Do you use ssh somewhere?

After exec cli, your shell script does not return to run the next line, sleep 2
To be exact, it no longer exists, because exec replaces the shell process by the new cli process.



I suspect you do not really want the effect of exec, and should remove it.



I am not really sure what you want to do, but assuming you want to run the command show config in cli, try just writing the command to it's input:



printf "show config" | cli


For similar, but really difficult cases, see expect

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...
