Apache Airflow Operators - Bash Scripting

Introduction

Bash scripting provides a powerful and flexible way to automate tasks within Apache Airflow. This guide will cover essential concepts and best practices.

Key Concepts

• Bash is a command-line shell scripting language.
• Operators: `and`, `or`, `not`, `in` are crucial for complex logic.
• Variables: Store values for reuse.
• Looping: Repeat tasks.

Operators and Examples

Here are some commonly used operators:

• `and` - Combine multiple conditions.
• `or` - Return true if at least one condition is met.
• `not` - Negate a condition.
• `in` - Check if a value is present in a list.

Example: `{ "variable": "value" } and { "variable": "another_value" }`

Practical Use Cases

- Automating data pipelines: Create, update, and delete data. - Monitoring and alerting: Check for issues and generate alerts. - Scheduling tasks: Run tasks on a schedule.
