The command "shutdown -s now" is used to initiate an immediate shutdown of a computer.

Here's a breakdown of what each part of the command means:

• "shutdown" is the name of the command used to manage the system shutdown process.
• "-s" is an option flag that specifies to shutdown the computer.
• "now" is a parameter that tells the command to initiate the shutdown immediately.

So, when this command is executed, it will immediately shut down the computer without any prior warning or delay. It is important to note that this command usually requires administrative privileges or root access to execute.
