kali-fetch is a screen fetch program that displays network interface parameters in your terminal that are specific to wireless operation. It will keep track of your wireless interfaces, and which mode they are in. When an interface is in Moniter mode, a syringe appears under that interface telling you that injection is possible. (Note that this only tests for monitor mode, not injection capability of your card. This is helpful when conducting wireless pentesting operations, especially when using multiple interfaces, such as MITM attacks. It is written in Python3 and very hackable for more diverse needs.
