The command "nginx -s reload" is used to reload the nginx web server without shutting it down. This command sends a signal to the nginx process to gracefully reload its configuration file and apply any changes made to it.

Here is a breakdown of the command:

• "nginx" is the command to invoke the nginx binary/executable file.
• "-s" is a flag/option that specifies that a signal will follow.
• "reload" is the signal to send to the nginx process.

When you run this command, it tells the nginx process to reload its configuration file, apply any changes, and continue serving requests. This is useful when you have made changes to the nginx configuration and want them to take effect without interrupting the web server's operation.
