I have the following file which called list.txt. This file contain the following:



AA --> TX1
BB --> TX2
CC --> TX3


Also, I have the following file which called A.txt. which contain the following text 



AA XXXXXXXXXXXXXXXXXXXXXXXX BB
XXXXXXXX CC


I would like to replace AA, BB, and CC with its equivalent values from the file list.txt, so the output is as follows:



TX1 XXXXXXXXXXXXXXXXXXXXXXXX TX2
XXXXXXXX TX3


How can I do that?

You can do this:



#!/bin/bash
for i in AA BB CC;do
var=$(grep $i list.txt | awk 'print $2')

 while read $i ; do 
 sed -i -e 's/'$i'/'$var'/g' A.txt; 
 done <A.txt
done


The output is as follows:



$cat A.txt
TX1 XXXXXXXXXXXXXXXXXXXXXXXX TX2
XXXXXXXX TX3

  • The response above assumes that --> is not exist in the list file. If it is an actual column in the list then you have to replace awk 'print $2' byawk 'print $3'.

    This is very brittle, it's will fall if the strings contain bash, grep or sed special characters. The first is easily fixed with quoting, the later two not so easily

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...
