Delete log files

When troubleshooting- or just for general cleanup- it’s nice to be able to delete old log entries so you know you’re looking at the right changes.

I’m embarrassed to say this but after 3 years of using VyOS I still have no idea how to clear the logs.

“delete log file” always returns “file not found” no matter what I specify- and nothing else I do seems to clear old log entries. I’m sure it’s something obvious that I’m just missing- can anyone fill me in on how to clear the logs?
