UNIX for Dummies Questions & Answers

HI!

I have a file containing a column of numbers with 69 rows.
I won't to factorize row 20 to 50 with 1.03
How do I do that?
(I'm a beginner as you easily can understand)

seems like a homework question.
ok show us what you tried.

I have

list/file containing:

10
20
10
45
43
named "test.txt"

This is what I won't to do.

10
20*1,03
10*1.03
45
43

and then crerate a new file with the modified data, named "test_mod.txt"

It is an extremly simple operation (I presume).
Best Regards!

Hi frebo,
this really is very simple.
but it seems like a homework assignment to me.
and as per the rules of this forums this is not allowed, unless and until you have tried your best for getting the answer.
So first post what you have tried on your own,

Regards,
Gaurav

I will be back

saying that a thing is strange is a relative term.
something strange for you may not be strange for someone else.

You are always welcome with your queries, but this forum strictly discourage any homework assignment where the aim is to get the answer without working hard for it. The proper way of learning is try it yourself first.

Now your hint,

You can use awk for it and use NR field in it.
NR is the current record number on which awk is operating.
