A very generic question but I am looking for the simplest way solve this very quickly and efficiently

I have a file with a very large number of lines which looks like this 



 451267 sample1.txt 
 157444 sample2.txt 
 134864 sample2.txt


and I want result where the file(same or new) looks like 



 451267 sample1 
 157444 sample2 
 134864 sample2





shell-script awk sed cut paste

    Simple and fast with cut cut -d. -f1 filename. Of if you prefer awk -F. 'print $1' filename If you want to know more about string manipulation see: mywiki.wooledge.org/BashFAQ/100

The easiest way to do this is with sed I believe.



sed 's/.txt//g' file



This command replaces the pattern '.txt' with nothing.

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...
