Streamline Your Workflow: Copy, Rename, and Share Files to Azure Blob Storage using Bash

Managing files can be a cumbersome task, particularly when you need to copy, rename, and upload them to cloud storage like Azure Blob Storage. In this guide, we’ll explore how to create an efficient Bash script that automates this entire workflow, saving you time and reducing human error.

The Problem

Imagine having a directory filled with CSV files named in a specific format, such as:

Delhi_20221234556.csv

Melbourne_20123456789.csv

Goa_1234567890.csv

Sydney_2022345689.csv

You need to remove all numbers from the filenames, upload these cleaned files to Azure Blob Storage, and then archive them with the current date. Initially, a script was written for just one city (in this case, Goa), which wasn't scalable.

The Solution

Here’s a step-by-step guide to improve and generalize the script to cover all specified CSV files in a given directory.

Step 1: Setup Your Environment

Make sure you have the following prerequisites:

Azure CLI: Ensure you have azcopy installed.

Directory Structure: The directory should contain your CSV files at /abc/def.

Archive Directory: The script will automatically create an Archive folder to move cleaned files into.

Step 2: Create the Bash Script

Below is the improved script that will automate the process for all files.

Step 3: How the Script Works

Directory and Archive Creation: The script defines the target directory and ensures the Archive folder exists.

Loop Through Files: It loops through each CSV file in the specified directory.

Rename Files: By utilizing parameter expansion, it removes the numbers and renames the files accordingly.

Upload to Azure Blob Storage: It uses the azcopy command to copy the cleaned file to the specified Azure Blob URL.

Archiving: The renamed file is then moved to the Archive directory with the current date appended to its name.

Important Notes

Handling Multiple City Names: This script does not currently address cases where there are multiple files sharing the same city name but with different numbers (e.g., Delhi_123.csv and Delhi_456.csv). A more robust version may need to implement additional logic to handle such situations.

Testing: Always test your scripts on a small batch of files to ensure everything works as expected before running it on your entire directory.

Conclusion

By automating the process of file management with a Bash script, you not only enhance your productivity but also reduce the likelihood of errors. Adapting this script for other directories or naming conventions can further streamline your workflow. Don’t forget to customize your Azure Blob Storage details in the script before running it!
