Efficiently Rename Files Sequentially with a Bash Script

Managing files in your system can sometimes become overwhelming, especially when you need to rename multiple files. If you find yourself wanting to rename files in the current directory and its sub-directories in a sequential manner, you're not alone! In this guide, we'll explore how to create a Bash script that allows you to rename all files by simply entering a string, resulting in filenames like STRING_001.jpg, STRING_002.jpg, and so forth.

The Problem at a Glance

Imagine you have a collection of files scattered in various directories, each with different names. You want to rename these files to a more structured format based on a user-defined string. The goal is to achieve sequential numbering regardless of whether the files are in the same directory or different directories. This solution will not only make your files more organized but will also give you a clearer overview of your documents.

Solution Breakdown

To tackle this problem, we’ll write a Bash script. Below, I’ll guide you through the necessary steps to achieve a fully functional script.

Step 1: Setting Up Your Script

Here's the core of our script to rename files:

Step 2: Breakdown of the Script

Let’s dissect what happens in the script above:

User Input: The script starts with a prompt asking the user to input a string which will be the base name of the files.

Finding Files: The find command is used to locate all the files (-type f) in the current directory and its sub-directories.

Numbering and Renaming: Using cat -n to number the files, the script enters a loop where it reads the filename and its number. It constructs the new filename in the format STRING_001, STRING_002, etc. using printf for proper formatting.

Renaming Command: Each resulting mv command is echoed to the console. This can be modified to run the command directly instead of just displaying it.

Step 3: Testing Your Script

Before running the script, create a directory structure with files you can test. Here's a quick setup you can use:

Run the script with ./your_script_name.sh and input your preferred filename:

Step 4: Execution

When you run the script, it performs the renaming of files as follows:

(Note: You must remove the echo keyword to actually perform the moves.)

Conclusion

And there you have it! A simple yet effective Bash script to rename files sequentially across multiple directories. This can greatly enhance your file management and provide better organization to your projects. Feel free to expand upon this script based on your specific requirements or integrate it into your routine tasks. Happy scripting!
