How to rename files in Linux like the ren command in Windows

I need to rename a bunch of files (more than 100) on an Ubuntu system, and want to know how to I do that when the pattern of the files is something like "Filename_01.jpg" to "NameOfFile_01.jpg" In Windows, I would type: ren Filename_*.jpg NameOfFile*.jpg Because of the convoluted way the various commands I have found (rename, mmv, etc.) work, and the syntax examples, I can't make heads or tails of those commands. I don't need to full explanation of how the command works, I just need the exact syntax to do this.
