File Processing Automation Workflow

This workflow is ideal for:

• Data Analysts: who need to process and analyze file data efficiently.
• System Administrators: looking to automate command execution based on file inputs.
• Developers: who want to integrate file handling and command execution in their applications.
• Automation Enthusiasts: interested in creating complex workflows without coding.
• Organizations: that require streamlined data processing and reporting.

This workflow addresses the challenge of automating the processing of binary files and executing commands based on their contents. It efficiently:

• Reads data from a specified file.
• Splits the data into manageable parts.
• Executes commands dynamically based on the processed data, saving results to an output file. This eliminates manual intervention and reduces the risk of errors in data handling and command execution.

1. Manual Trigger: The workflow starts when the user clicks 'execute'.
2. Read Binary File: The workflow reads the contents of a binary file located at /home/n8n/filelist.txt.
3. Move Binary Data: The binary data is prepared for further processing.
4. Function Node: A function splits the file data into an array and calculates the size of the data, storing it in dataSize.
5. Execute Command: For each item in the array, a command is executed to echo the file name into /home/n8n/n8n-output.txt.
6. Conditional Check (IF): The workflow checks if there are more items to process based on dataSize. If there are more items, it continues executing commands; if not, it proceeds to the NoOp node.
7. No Operation (NoOp): This node acts as a placeholder, indicating the end of the workflow when no further processing is needed.
