A list of scripts and programs that can fetch information and print it to stdout. Possible use cases for such utilities:
- Check information on the CLI
- For use in custom fetch scripts
- For use in notifications
- For use in status bars
Please open an issue or send a pull request to add to the list or report entries that are outdated or shouldn't be on the list in the first place.
These are projects that contain a multitude of fetch scripts / programs. Note that, depending on their intended purpose, some of these might have additional files and/or functionality that goes beyond printing information to stdout. It should still be possible to use them for that, however.
