Streamline Data Logic with Execute Command and Conditional Branching
detail.loadingPreview
Automate command execution and dynamically control workflow paths based on command output. This n8n setup allows for complex decision-making within your automated processes.
About This Workflow
This n8n workflow snippet demonstrates a powerful combination of command execution and conditional logic. It starts by running a command-line instruction, capturing its standard output. This output is then parsed as JSON and used to inform a decision point. The 'IF' node evaluates a specific value from the parsed JSON, allowing your workflow to branch accordingly. This is ideal for scenarios where external system responses or dynamic data need to dictate subsequent actions, ensuring your automations are intelligent and responsive.
Key Features
- Execute Arbitrary Commands: Run any command-line tool or script directly within your workflow.
- Dynamic Data Parsing: Seamlessly interpret command output as structured JSON data.
- Conditional Workflow Branching: Create intelligent decision points based on parsed data values.
- Flexible Logic Integration: Combine external command results with your existing n8n automations.
How To Use
- Add 'Execute Command' Node: Drag and drop an 'Execute Command' node onto your canvas. Enter the command you wish to run in the 'Command' field. For example,
echo "{ \"value1\": true, \"value2\": 1 }". - Add 'To Flow Data' Node: Connect the output of the 'Execute Command' node to a 'To Flow Data' node. This node will parse the command's standard output into a usable format.
- Add 'IF' Node: Connect the output of the 'To Flow Data' node to an 'IF' node. Configure the conditions using expressions like
={{JSON.parse($node["Execute Command"].data["stdout"]).value1}}to compare against a desired value (e.g.,true). - Define Branches: Configure the output paths of the 'IF' node for when the condition is met and when it is not, connecting them to subsequent workflow steps.
