Running Redis Cluster on macos locally
#!/bin/sh
# when installing redis from brew, it doesn't come with `utils` folder
# and because of which it's rather difficult to run redis cluster locally
# (`utils` folder has `create-cluster` script files, which automate the creation
# startup, stopping of redis cluster)
# this script is a workaround for that, basically, it checks if `utils` folder is
# there or not, if not, it downloads it and makes the necessary changes
# it assumes, you are running this on macos, with zsh shell
# check if redis-cli is installed
