Change text using bash

Question

I have a program called gamemode, and to check if it's running, you can use gamemode -s, which outputs either "gamemode is active" or "gamemode is inactive".

I want to change "gamemode is active" to "<an icon that doesn't show on this website>" and change "gamemode is inactive" to some other icon.

Answer 1

sed would be easiest:

gamemode -s | sed -e 's/gamemode is active/<active icon>/' -e 's/gamemode is inactive/<inactive icon>/'

Answer 2

gamemode -s | awk '{print (/inactive/ ? <inactive icon> : <active icon>)}'
