shutdown:tldr:41728

The command "shutdown -r "+${5}" is used to reboot a computer after a specific period of time.

Here's a breakdown of the command:

• "shutdown" is the main command used to shut down or restart a computer.
• "-r" is an option for the "shutdown" command, which indicates that the computer should be restarted.
• "+${5}" is a parameter that specifies the time delay before the restart occurs.

The "+${5}" part can vary depending on how it is used in the context of a script or command line. In this case, it seems like it is being used to refer to the value of the 5th argument passed to the command. The actual time delay provided by the argument might depend on the system or script using the command.
