How can I find a list of wifi interfaces that could be used by hostapd?
This doesn't work - I don't see my wifi interfaces listed:
☀ cat /etc/network/interfaces NewMod master
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
This kind of works - but I can't see which are wireless (except they start with wl)
☀ ifconfig NewMod master

Is there a better way than assuming interfaces starting with "wl" are wifi?
Bonus points for a quick explanation of why they don't show up in /etc/network/interfaces. For these extra interfaces, do they have reliable names between reboots?
Basically I want to provide a list of interfaces so someone can choose which to hostapd with.
Thanks!

You can use iwconfig but iwconfig is depricated.
Now way is this:
iw dev | grep -Po '^sInterfacesK.*$'

Look at inet address. Only device here that might be working wireless is wlp3s0. Others do not have external ipv4 address.
Also look the hardware address . Compare with output from other system descriptors like lspci.
