Managing multiple SSH keys for our accounts and projects could become challenging, and running the SSH CLI command with the secret key option every single time could also be tedious. Here's the clean and easy way to manage SSH keys by hosts.

Therefore, I decided to write a simple script to set up and/or switch a git user config with one command.
