What is SSH?

Secure Socket Shell, otherwise known as (SSH), allows us to access our directories and files on our operating system, whether it's on our local development environment or our live web server.

In order to do this on macOS, we need to launch the Terminal application. On Windows, we can use the Bash application that was explained earlier.

We can execute commands with SSH to do this; for example, we can change to another folder/directory using the following:

cd mydirectory

Alternatively, we can create a new folder/directory using this:

mkdir mydirectory

These are just some examples of SSH commands, and I encourage you to take a look into this.

When we are doing this development, especially where we are using dynamic code such as PHP, we need to be able to add other tools using the command line.
