How do I add numbers from two txt files with Bash?












1















I have a txt file that contains some numbers like this: 



1  

2  

3  

4  

5


And I have another txt file that contains the same number of lines, but with other numbers:



6  

7   

8  

9  

10


I want to add them together, namely 1+6, 2+7, 3+8, etc.. How do I write the script?






bash shell-script text-processing numeric-data

    Do you really want to do this "with Bash" - or are you looking for a command line solution more generally?

    You will get a much more friendly reception and much better help here if you show what code you have tried so far and describe what problems you were having with it. Without code, your question looks like a request for free consulting and many people don't like that.
