How to configure Crontab on CentOS 7?

Cron jobs are used to schedule commands for recurring execution. We can program instructions or scripts to execute on a regular basis at a predetermined time. The daemon known as the cron service operates in the background. In order to configure the crontab, we must open crontab with the text editor and enter the following command:

configure crontab centos 7

Every cron command consists of five time and date fields, a user name field (optional), and a command field if this is the system crontab file. When the time indicated by the time/date fields coincides with the current time, commands are carried out. Let’s look into the details:

1. To see the current user’s crontab entries, run the following command.

configure crontab centos 7

2. To access the particular user’s crontab entries, we can use the below code:

configure crontab centos 7

3. Use the following command to delete or remove every crontab job:

configure crontab centos 7

4. We can use the below code to create the cron job backup:

5. The below code restores Single-user backups from backup using the code:

6. We can use the below code to store all user cron tasks in a Centos backup:
