rdev

The rdev command in Linux is used to change the root device of a Linux system. It is a powerful tool that can be used to change the boot device of a Linux system.

The rdev command is used in the following syntax:

rdev [options] [device]

The device is the device name of the new root device.

The options can be used to specify the following:

• -f : Force the change, even if the new root device is not bootable.

• -v : Be more verbose.

For example, to change the root device to the device /dev/sda, you would run the following command:

rdev -f /dev/sda

This command will change the root device to the device /dev/sda. If the device /dev/sda is not bootable, the system will not boot.

To be more verbose about the change, you would run the following command:

rdev -v -f /dev/sda

This command will change the root device to the device /dev/sda and print more information about the change.

The rdev command is a powerful tool that can be used to change the boot device of a Linux system. It is a versatile command that can be used to change the root device to any device that is supported by the Linux kernel.
