Welcome Baber,

I have a few to questions pose in response first:-
  • Is this homework/assignment? There are specific forums for these.
  • What have you tried so far?
  • Have you got some sample input & desired output?
  • 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.

Wow, that's a lot of cating files, and I'm not sure you need all of it. Could you tell us what the plan is? It is much easier to read values, count lines etc. than you are try to do. If you can explain your logic then we might achieve a better bit of code.

So far, I think:-
  • Count lines in x
  • Subtract the value in file y
  • Write the answer back to y
  • Get records from server.log with the string hasan
  • ............ and then it all goes weird with the -n flag and the value from before.
Can you explain a bit better what you need?

It would be good to know the answers to the other questions else I might go off in a way you don't understand and cannot support later.



Thanks,
Robin
