crontab: Replace the current crontab with the contents of the given file.

crontab

$ crontab ${filename}

try on your machine

The "crontab" command is used to create, edit, or display the cron jobs for a user. Cron jobs are scheduled tasks that run automatically at specific intervals.

In the command "crontab ${filename}", the ${filename} is a placeholder for the name of a file that contains the cron job entries. It can be an existing file that you want to set as the cron job configuration, or a new file that you want to create and use as the configuration.

When you execute this command, the crontab utility will read the contents of the specified file and apply them as the user's cron jobs. The file must follow the specific cron syntax, where each line represents a separate cron job entry.

Overall, this command is used to import or update the cron jobs for a user from a file.
