Quick macOS alerts from the shell
Yo Scheduler is a free macOS utility that lets you trigger system notifications directly from the command line. It’s built for people who want lightweight, scriptable alerts without launching a graphical app. The interface is simple and focused, so you can insert notifications into build scripts, maintenance tasks, or automated workflows quickly.
Notable capabilities
- Schedule alerts to appear at a specific time or after a delay, useful for reminders or timed notices.
- Customize notification content including the headline, body copy, and optional metadata.
- Integrate the tool into shell scripts, cron jobs, or CI pipelines to automate status updates.
- Accept a range of message types and formats so you can tailor alerts to different workflows.
Common scenarios for use
Yo Scheduler is useful for developers and system administrators who need compact, script-driven reminders:
- Notify you when long-running scripts finish or when a backup completes.
- Pop an alert for recurring tasks or stand-up reminders without opening a calendar app.
- Emit status messages from automated jobs so you get immediate feedback on success or failure.
Basic command examples
To send a simple notification:
- yo-scheduler --title "Build complete" --text "All tests passed" --delay 0m
To schedule an alert at a specific time:
- yo-scheduler --title "Standup" --text "Daily meeting in 10 minutes" --at "09:50"
Adjust flags to suit your environment; the command syntax remains minimal so it’s easy to call from other scripts.
