Cron jobs are scheduled tasks that run automatically at defined times.
They are used to perform recurring actions without manual intervention.

Cron jobs run on the server and execute commands or scripts.

How Cron Scheduling Works #

Cron jobs use a time format that defines:

• Minute
• Hour
• Day of month
• Month
• Day of week

You can:

• Use common scheduling presets
• Or define custom schedules

Incorrect schedules can cause tasks to run too often.

Creating a Cron Job #

To create a cron job:

1. Choose a schedule
2. Enter the command to run
3. Save the cron job

Commands must be correct and executable.

Command Examples #

Cron jobs often run:

• PHP scripts
• Shell commands
• Application-specific tasks

Always use commands provided by trusted documentation.

Output and Notifications #

Cron jobs may:

• Produce output
• Send error messages by email

You can configure where output is sent.

Ignoring errors can lead to hidden problems.

Performance and Limits #

Poorly configured cron jobs can:

• Consume server resources
• Slow down websites
• Cause repeated errors

Do not schedule tasks more frequently than necessary.

When Not to Use Cron Jobs #

Do not use cron jobs if:

• You do not understand the command
• A plugin or application does not require it
• Tasks can be handled automatically by the software

Unnecessary cron jobs create risk.

Security and Responsibility #

You are responsible for:

• Correct commands
• Safe schedules
• Removing unused cron jobs

ProRedLine does not monitor individual cron jobs.

Common Issues #

• Tasks running too frequently
• Incorrect command paths
• Permission errors
• No output or silent failures

These issues are usually configuration-related.
