Bulk Rename Files from List?

[rive22]

For this little project, I have many folders with many files in each folder.

I have a individual lists of what the files names should be for each folder.

It's not as simple as adding, removing, or replacing characters as there is no pattern.

What I need is a script that will take all the names from file.txt and rename all the files in folder1, etc, according to the list.

The file names in the list each start with a number and so do the files in the folders, those numbers match and that's how they should reference each other.

I am open to batch, bash, etc, anything that works.

Any ideas?

Thanks
