The command is working after re-copy-pasting it after sending this email. Seems it was related to the first copy-buffer or somesuch.

The system is an olimex teres running armbian ubuntu 18, and has had the radio disabled using 'nmcli radio all off; sudo systemctl disable NetworkManager;" for some time now. it is running the same install it was when the keyboard, which has a usb-programmable avr chip, was sending incorrect keycodes. the incorrect keycode behavior has stopped.

I have just videotaped bash removing a command from my bash history every time I execute it, using a phone that has been in airplane mode since factory reset, and also most of its life since purchase.
