I'm trying to get to know awk a bit better.
So i'm trying to get used to calls saving me a grep invocation just to get a specific part of a single line.
This said, i want to get the current screen resolution according to xrandr's output.
So, the desired output would be: 1920x1080
So, in a first attempt, and according to another thread, i tried to apply and started with excluding those lines not containing the asterix.
They seemed to work quite fine, just that they didnt print any output.
Then i thought, maybe its better to just check if the line contain the asterix and print just that one.
What a change, but it prints the first column from every line.
Also, playing around with: (switching && with || and \* with * and >= with == / <=)
Didnt change much, or i missed the working combination of those.
You're not too far off:
Don't surround the testing pattern with { } - it will become an action, then...
And, if using printf, don't forget the \n line terminator.
I have a 6 column array with 2 million rows that looks like this:
1 1089699 rs6686003 G A g
1 1090557 rs7553429 A C c
1 1094738 rs4970362 A G a
1 1099342 rs9660710 A C c
1 1106473 rs4970420 G A a
1 1108637 rs4970421 G A g
1 1119858 rs1320565 C T c
