I have such a script in ~/draft



$ cat test.sh
#! /usr/local/bin/bash

for i in ./*;do
 echo $i
done


The chunk of code are stored in test.sh,

when I run it 



$ bash test.sh
./first.html
./second.html
./test.sh
./third.html


So I run the script name test.sh and get the output.



Alternatively, I could run the command directly as:



$ for i in ./*; do echo $i; done
./first.html
./second.html
./test.sh
./third.html


The second chunk get the identical results.



Since the preceding codes resides in file test.sh, what's the filename where the command for i in ./*; do echo $i; done live?






bash

          Commands don't have to be stored in a file to be executed - the interpreter (in this case bash) can simply read the command line into memory like it would read a script file (with some minor caveats related to buffering) and then execute it in exactly the same way.

                    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...
