The First Script That Needs To Be Written Is Automating The Shutdown P The first script that needs to be written is automating the shutdown procedure. Write a script that will perform the following tasks: Prompt the system administrator for all valid input parameters. Ask if a wall needs to be sent, and if yes, send the message. Ask if this is a shutdown or reboot, and process appropriately. In addition, take this opportunity to describe the various UNIX run levels, what each level is used for, and how to boot to a specific run level. Must be original work and APA formatted references and double spaced.
Paper For Above instruction Automation Script for UNIX Shutdown and Run Levels Explanation The First Script That Needs To Be Written Is Automating The Shutdown P Automating system shutdown procedures is essential for maintaining the integrity and availability of UNIX systems, especially in environments that require regular maintenance or updates. Writing a script to perform this task involves prompts for user input, conditional decision-making, and execution of system commands to either shut down or reboot the machine, along with the ability to notify users via wall messages if necessary. Additionally, understanding UNIX run levels is crucial for effective system management, as they define the state of the machine and what services are active during each level. Development of the Shutdown Automation Script The script begins by prompting the system administrator for input parameters necessary to execute a controlled shutdown or reboot. It should request the administrator to specify whether a wall message needs to be broadcasted to all logged-in users. If affirmative, the script should prompt for the message content and utilize the wall command to send alerts across all terminals. This feature facilitates user awareness and minimizes unexpected disruptions. Subsequently, the script asks whether the action is to shut down or reboot the system. Based on the input, it executes the respective command — shutdown -h now
