I did an upgrade 2 nights ago to my installation (on hard drive, dual boot), and if memory serves the upgrade included the package "kali-full" which I'm sure had a lot of updated apps, drivers, etc.

So yesterday I try to run airmon-ng like I always do, and I am getting these very odd "grep" errors. Wireless seems to be working, but a lot of wireless kali apps are not.

I am on my phone at the moment. So I can't paste the output. But I will add this output when I get home.

Was just wondering if anyone else was seeing this....
