I'm up to reinstall Arch on my laptop while I have a bit of a time and I've encountered an interesting question to ask.



Is there any way to check my laptop battery status without installing acpi package? (as I'm currently offline without charger and I can't get neither of them)



I thought that system should keep track of a battery level somehow. So is it possible to display that info in CLI?






arch-linux console

    Have a look at the files in /sys/class/power_supply/. May or may not work for your particular hardware.

The kernel provides this information through /sys/class/power_supply/BAT0/capacity



Simply cat this path to get the information (in percent of your batteries capacity):



cat /sys/class/power_supply/BAT0/capacity


For an live view you can combine cat with the command watch. The following command provides you a an, updated, live status of your batteries capacity:



watch -n0 cat /sys/class/power_supply/BAT0/capacity

            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
