Extract lines from a file 1

[Diogo]

Hello.

Can some one help me.

I have one file with 30 lines, and i want to obtain the lines between line number 15 and line number 18.

Is there any way?

Thanks any way.

Hi. See the sed solution in Thread822-363893

And the awk way:
awk 'NR==15,NR==18;NR>18{exit}' /path/to/input

Hope This Helps, PH.

hi, I wanted to do something similar to this, but I want to extract a random line number. How would I go about doing this? I have tried to use:

sed -n $RANDOMp sonnets.txt

but that doesnt seem to work. Thanks in advance

Also, how would I apply modulus to it. Because I want random to return a number <2156. I want put $RANDOM%2156, but I am not sure how to use modulus in scripting. Thanks again

nevermind, I answered my own question. My solution was:

sed -n $(($RANDOM % 2156))p filename

if anyone was interested =)
