Answer:
sudo mount -o loop vdisk.img /mnt/newvdisk
This command uses the mount command to attach the virtual disk image to the specified mount point. The -o loop option tells the mount command to treat the file as a block device, which is necessary for mounting disk images.
If the /mnt/newvdisk directory does not already exist, you can create it with the following command:
sudo mkdir -p /mnt/newvdisk
After the virtual disk image is mounted, you can access the files on the disk as if they were stored on a physical disk. When you are finished, you can unmount the disk image with the following command:
sudo umount /mnt/newvdisk
Note that these instructions assume that you are using a Linux operating system that uses the mount and umount commands to attach and detach file systems. The exact commands and options may vary depending on your specific operating system and version.
