awk prints $2 to what I expect, but when I compare $2's value to same it returns false
When I am giving the following command -
ip -br -c addr show | awk '{print $2}'
It returns something like this output -
UNKNOWN
UP
DOWN
UP
UP
UP
UP
but when I want to only print the ones which are UP and I say -
ip -br -c addr show | awk '$2 == "UP"'
it does not return anything.
I have used awk with such comparisons and it works, here I am wondering may be -br does not return a comparable string. Or is there something I am doing wrong.
Solution
This is because you tell ip command to add color codes to your output by using the -c option:
-c[color][={always|auto|never}
Configure color output.
Remove -c, and ip -br addr show | awk '$2 == "UP"' will work.
Or, you may match the green color code:
ip -br -c addr show | awk '$2 == "\033[32mUP"'
