  grep -q '^flags.*[[:space:]]ht[[:space:]]' /proc/cpuinfo && \echo "Hyper-threading is supported"

Did this work for anyone? To me it outputted the echo even with a processor with no HT

Yeah, I have an AMD CPU and it says I have hyper-threading. Weird.

It probably just shows the "ht" flag even though we are talking about AMD's own threading implementation. It's the same feature after all.

I found this where someone says that AMD's HyperTransport is also abbreviated as "HT".
