[dantebarba]

Is it possible to use the unix cron shortcuts on both cron expressions?.

Examples of shortcuts: @daily @hourly @weekly

Hi, I have updated this project to the most current version of rclone and built in cron shortcuts.

I would say that those aliases should be supported as long as alpine's crontab supports them.
The only check the image is doing is if the argument is set or not. It's opaque.

I am not sure what is the support status of that crontab extension.
