A final step in the script is to schedule the script to run at a time interval. This can be daily, weekly, hourly, or at a specific time. This can be done using the cron job on Linux systems. cron is used to schedule a repeated event, such as cleaning up directories, backing up databases, rotating logs, or anything else you can think of.
To view the current jobs scheduled, use the following command:
crontab -l
To edit crontab, use the -e switch. If this is the first time you are running cron, you will be prompted to use your favorite editor (nano or vi).
A typical crontab consists of five stars, each one representing a time entry:
|
Field |
Values |
|
Minutes |
0-59 |
|
Hours |
0-23 |
|
Day of the month ... |
