You can run a shell command in Jupyter Notebook or Google Colab with IPython by prefixing it with the ! character or % to use magic commands. A list of useful magic commands for data scientists is described in Top 8 magic commands in Jupyter Notebook. You can install Redis and its Python client using the `!curl` and `%pip install redis` commands, respectively. To start the Redis server, run the `./redis-stack-server-6.2.6-v7/bin/redis-stack-server --daemonize yes` command. To verify that Redis is running, create a connection to it with the Python client and ping the server using the `client.ping()` method. You can then read and write data to Redis using its command functions such as `set`, `get`.
