Jupyter Kernel : Is there a way to rename them?

I mis-typed the name for the kernel while issuing: python -m ipykernel install --name and the wrong name is showing up the Jupyter's "Change kernel" menu. Is there a way to change just the name (without unstalling and installing it with the right name again)? I could not find where Jupyter is storing the names of the installed kernels. That could perhaps be edited?
Thanks, etc.

You can use the kernelspec command to get information about the installed Kernels for your installation.

The command jupyter kernelspec list will provide you a list of the installed Kernels, something like: 

Available kernels:
  python2          /Library/Python/2.7/site-packages/ipykernel/resources
  redisworkshop    /Users/tague/Library/Jupyter/kernels/RedisWorkshop
  bash             /Users/tague/Library/Jupyter/kernels/bash

The display name for a kernel is found in the kernel.json file in the corresponding directory for the kernel.
Edit the display_name property in the kernel.json file and it will change the display name next time you start Jupyter.
