We have an IoT command server and connecting to one of the devices (for maintenance, logs or whatever) involved two manual lookups in the output of two commands and then finding your match in both. I was sick of this one day and with some grep, sed, awk and finally fzf, you could just sort of type the device's name and press "enter" to connect. People's reaction when I showed them was basically WHAT IS THIS MAGIC?!?
