This command is used to create a logical volume using LVM (Logical Volume Manager) in Linux. Here's the breakdown:

sudo: It stands for "superuser do" and is used to execute the following command with administrative privileges. It asks for the password of the superuser or a user with sudo privileges.
lvm: It's the command-line tool for managing Logical Volume Manager.
lvcreate: It is a sub-command of lvm used to create a new logical volume.
-L ${10G}: This option specifies the size of the logical volume to be created. ${10G} is a variable representing the size of 10 gigabytes. So, this command will create a logical volume with a size of 10 GB.
${vg1}: This is another variable representing the name of the volume group in which the new logical volume will be created. The volume group is a pool of physical volumes (hard drives or partitions) from which logical volumes are created. You need to replace ${vg1} with the actual name of the volume group.

Overall, this command creates a new logical volume of 10GB within the specified volume group.
