Welcome aynar,

I have a few to questions pose in response first:-
  • What have you tried so far?
  • What output/errors do you get?
  • What OS and version are you using?
  • What are your preferred tools? (C, shell, perl, awk, etc.)
  • What logical process have you considered? (to help steer us to follow what you are trying to achieve)
Most importantly, What have you tried so far?

There are probably many ways to achieve most tasks, so giving us an idea of your style and thoughts will help us guide you to an answer most suitable to you so you can adjust it to suit your needs in future.

We're all here to learn and getting the relevant information will help us all.

until now i've changed the output to that


but i have no idea how to do the rest
i have the idea but i don't know how to apply it
i dont even know if it's possible to do a loop that verify in the second column and and show me for each ip the total of the corresponding number

If you just want them listed together, the sort command would do that. if you only want "". grep is something to try.

That's where I stop for now. You will learn it and retain it much better if you look up those commands and experiment with how to use them.

P.S. Just saw that you removed a few things from each line. That isn't necessary.
