Zeit is a Qt-based graphical frontend for managing scheduled commands on Linux. It provides an interface to two traditional scheduling utilities: crontab for recurring tasks and at for commands that need to execute only once.
The application brings these scheduling mechanisms together, allowing users to manage routine activities and occasional jobs without manually editing crontab files or entering scheduling commands in a terminal. It is particularly useful for people who want to automate straightforward tasks while retaining the familiar scheduling facilities provided by Linux.
Zeit works with the underlying cron and at utilities rather than implementing a separate scheduling service. The relevant services must therefore be installed and configured for scheduled jobs to execute.
This is free and open source software.
Key Features
- Add, edit and delete recurring cron jobs using graphical controls instead of manually modifying crontab entries.
- Manage one-time commands through the at utility, including adding new jobs and removing scheduled commands.
- Add, edit and delete crontab environment variables used to configure the execution environment for scheduled tasks.
- Copy existing tasks and environment variables to simplify the creation of similar scheduling entries.
- Provides alarm and timer functionality alongside conventional cron and at job management.
- Supports optional administrative operations for managing privileged scheduled tasks.
- Integrates with PolicyKit through KDE Frameworks components when the relevant support is enabled during compilation.
