Do you need to restart cron?
No you don’t have to restart cron , it will notice the changes to your crontab files (either /etc/crontab or a users crontab file).
What is the difference between cron and Crond?
The main difference is that /etc/cron. d is populated with separate files, whereas crontab manages one file per user; it’s thus easier to manage the contents of /etc/cron. d using scripts (for automated installation and updates), and easier to manage crontab using an editor (for end users really).
Is it recommended to restart cron or Crond after each new schedule?
When I schedule a job, some seem to be applied immediately, while others after a reboot. So is it recommended to restart cron ( crond) after adding a new cron job? How to do that properly (esp. in a Debian system), and should that be done with sudo (like sudo service cron restart) even for that of normal users’?
What is the name of the cron command?
Cron is named after Greek word “Chronos” that is used for time. This guide provides an overview of how to schedule tasks with crontab and how to using cron’s special syntax. Above all, a crontab file is a simple text file containing a list of commands meant to be run at specified times. It is edited using the crontab command.
How is a cron file edited using crontab?
It is edited using the crontab command. The commands in the crontab file (and their run times) are checked by the cron daemon, which executes them in the system background. Each line of a crontab file is either “active” or “inactive”. An “active” line is an environment setting, or a cron command entry.
Is there a way to notify Cron when something has changed?
As mentioned, crontab -e, the preferred method, will notify cron that something changed. However, cron “wakes up” every minute to see if it has tasks for that minute. It also scans /var/spool/cron/crontabs and will reload any files with an updated ‘mtime’ (modified time, meaning the file contents must have been updated).
