    @Kusalananda and those seeing a VTC duplicate to unix.stackexchange.com/questions/432332/…, it sounds to me like they want to remove/delete lines that end in digits, not "remove just the digits"

    I still want to know how many digits (s being used twice in the Q/title) are needed at the end to remove the line; 1, or more?

Very simple to do:



awk '/[^0-9]$/ print ' inputfile


Or, if you care to preserve empty lines, 



awk '! /[0-9]$/ print ' inputfile

    Or in case you are interested in grep too, following simple grep may help also.



    grep -v '[0-9]$' Input_file

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.
