Custom Prefix Application on Linux Files -- 2

I require a skilled Linux bash scripter to create a script that efficiently renames multiple files. This process should add a prefix to the filename, specifically "FileName_".

Key elements of the project are:
- Create a bash script
- This script should target and rename multiple files
- The renaming process must add a custom prefix - "FileName_"
- Ensure accuracy and efficiency

Ideal skills:
- Expertise in Linux bash scripting
- Knowledge in file management and renaming
- Attention to detail and accuracy
- Efficiency in script execution.


Our files have the flowing name format 1.file 2.file 3.file 4.file etc.
When renaming it should be done in a custom format each time for ex New.fileE1.file New.fileE2.file
New.fileE3.file
