I was searching for an application to let me rename files on Ubuntu. Windows makes it easy… You just need to select the bunch of file and press F2 to batch rename them. I am using PrefixSuffix application for the same purpose on Linux.
Do let me know if you find a better alternative!

Try thunar:
sudo apt-get install thunar
You will end up with a new menu entry Applications >> Accessories >> Batch Rename
