The title is basically my question. Is it possible to put a process into the background from another background process with bash?



For instance, if we have the following code:



function check_if_server_running 
 while [ server_running -ne true ]
 curl localhost:8000
 done
 bg %-


check_if_server_running &
./startServer

# Some other code...


Could we replace bg %- with something to make the ./startServer run in the background once it's up? Normally bg %- makes puts the last process in the background but it is not working for me






bash

          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...
