Why should a regular user edit his personal crontab by using the command crontab instead of just editing his crontab file manually?

  • A. Because user specific crontab entries are stored in a common database and must be extracted before editing.
  • B. Because crontab starts the cron daemon in case it is not running due to no other crontab entries existing.
  • C. Because user specific crontab entries are stored in a special directory which is maintained by the cron daemon and not writable for regular users.
  • D. Because crontab collects information about all users crontabs and recommends similar commands used by other users of the system.

The correct answer is A. Because user specific crontab entries are stored in a common database and must be extracted before editing. The crontab command is used to manage a user's cron jobs, including editing, displaying, and removing cron jobs. By using the crontab command, the user can ensure that the cron job is properly extracted from the common database and edited, rather than manually editing the file and potentially causing issues with the formatting or storage of the cron job in the database.
