How do you renaming multiple files with a batch file

[AgentEddie99]

Hi forum,

 

I was wondering does anyone know how to rename multiple files using a batch file?

 

So more details:

"image.jpg._10-05-2016-04-13-33_$ninja" is the file, would like to remove the "._10-05-2016-04-13-33_$ninja" but the only issue is that the next file is named "fish.jpg._10-05-2016-04-13-43_$ninja" how do I remove all of the ._10-05-2016-04-13-33_$ninja.._10-05-2016-04-13-34_$ninja,._10-05-2016-04-13-35_$ninja._10-05-2016-04-13-36_$ninja etc.. off the end of all of the files??????

 

Thanks would be a great help.
