  • 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.


Kind regards,

rbatte1... This is not homework question.
1) did not touch unix for long time.
2) I tried prev posts here. but none of them have space in a column value. So did not get the required results.
3) So much of other deadlines to meet so not able to think properly.
