For some reason my output of join is strange and scrambled; here is the command I use: 



join -t, -j 1 -o1.1,2.2,1.2 f1 f2


Where f1:



1,87


and f2:



1,337


The output is:



,8737


and I am at loss as to why the output of join is not as expected. I have checked my locale already, with no luck.



Any ideas?

    Does the file have DOS line endings (CR LF)? Add the output of join -t, -j 1 -o1.1,2.2,1.2 f1 f2 | od -c please.

Your data file are DOS text files. Each line has a trailing carriage return character.



The output that you expect is



1,337,87


but since there is a carriage return after the 7 in 337 (from the DOS line-ending in the second file), the cursor moves back to the start of the line before printing ,87, overwriting 1,33 there.



Run dos2unix on the data files to convert them to Unix text files, or instruct whatever program that creates them to create Unix text files.

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...
