The main difference between "shutdown -h" and "shutdown -now" is the behavior of the shutdown command. When using "shutdown -h," the system will initiate a shutdown process and then halt the system once all processes have been properly terminated. On the other hand, "shutdown -now" will immediately initiate the shutdown process without waiting for processes to be properly terminated, potentially leading to data loss or corruption. It is generally recommended to use "shutdown -h" to ensure a safe and orderly shutdown of the system. **
