New-port alerts
A port that starts listening while portop runs is marked in the table; --watch-new also raises a desktop notification.
Marks
New listening ports are highlighted until you press n. The first scan after start-up marks nothing.
Desktop notifications
| System | Shown with |
|---|---|
| Linux | notify-send, when installed |
| macOS | Notification Center |
| Windows | A toast shown as portop with its icon; Microsoft Store installs show it as Windows PowerShell |
Without a notifier nothing happens; the table still marks the port. Enable it permanently with watch_new: true.
