Hi everyone,

I am having a problem with awk.

I have a file of which I want to print only certain lines.

The lines to print are determined by an array.

so something like

for runs in ${options[@]}
do
awk 'NR==$runs' '{getline; print $0}' myfile
done

in options would be something like {1 2 3}, which would mean that in this case I want to print the 1st, 2nd and 3rd line of myfile

This code does not work, it does absolutely nothing.
Does anyone have an idea?
