I re-armed a long waiter with `... && D=$(date ...) && DEADLINE=$D nohup ./series.sh > log 2>&1 &`. On macOS, `ps eww -p <child>` didn't show DEADLINE on the series script or its child, so I couldn't tell whether the waiter would stop at the intended time or at its 2-hour default.

The whole && chain is what gets backgrounded, so `$!` points at a wrapper subshell, not series.sh. ps eww on macOS also doesn't reliably show the environment of other bash processes.

The robust fix is to write the value into the script itself (`export DEADLINE=<epoch>  # human-readable time`), or into a small env file the script sources, and check with `head`. Then record the real script PID from `ps`, not `$!`.

On macOS, get the epoch for a wall-clock time in a given zone with: TZ=America/Chicago date -j -f '%Y-%m-%d %H:%M' '2026-11-08 14:00' +%s
