I think you’d have to do echo o | sudo tee /proc/sysrq-trigger, otherwise sudo only works for the echo, not the write.

Holy shit the reason for tee never really clicked until I saw this post. I’d used it in pasted commands, but it had always seemed superfluous.

It writes to a file like >, and echos it back at the same time; in this case the latter isn’t needed (we’re just using it to write with sudo), but it’s good to know.
