The cron job syntax consists of five fields that specify the time and date of execution, followed by the command or script to run. The fields are: minute, hour, day of month, month, and day of week. Each field can have a specific value, a range, a list, a wildcard (), or a step value. The wildcard () means any possible value for that field. The option B sets the minute field to 0 and the hour field to *, which means the script will run at the 0th minute of every hour, regardless of the day, month, or weekday. This is equivalent to once per hour. The other options are either invalid syntax or do not match the desired frequency. For example, option A sets all fields to *, which means the script will run every minute of every hour of every day, month, and weekday. Option C sets the minute field to * and the hour field to 0, which means the script will run every minute of the 0th hour, or once per day at midnight. Option D has a typo (o instead of *) and option E sets the day of month field to o, which is not a valid value. References:

The /etc/printcap file on a BSD system defines the printers that are available by the Ipr printing system. The Ipr printing system is a BSD-compatible printing system that uses the lpd daemon to manage print jobs and spooling. The /etc/printcap file contains a series of entries, one for each printer, that specify the printer name, device, options, and filters. The format and syntax of the /etc/printcap file are described in the printcap(5) manual page. References:
