asr:tldr:73006

This command is used in macOS to perform a restore operation to a target volume using Apple Software Restore (ASR) with administrative privileges (hence the "sudo" command).

Here's the breakdown of the command:

• sudo: This is a command that allows a user with administrative privileges to execute commands as the superuser or another user.
• asr: This is the command-line utility for the Apple Software Restore tool, which is used for various disk management and restore operations.
• restore: This is the specific action of the ASR command that performs a restore operation.

The options that follow are:

• --source ${image_file-dmg}: This specifies the source of the restore operation, which is the disk image file (with a .dmg extension) to restore from. The ${image_file-dmg} is a placeholder that should be replaced with the actual path to the disk image file.
• --target ${path-to-volume_file}: This specifies the target of the restore operation, which is the volume or disk to restore to. The ${path-to-volume_file} is a placeholder that should be replaced with the actual path to the volume or disk.
• --erase: This option indicates that the target volume should be erased before the restore operation. This means any existing data on the target volume will be deleted and replaced with the contents of the source disk image.

Overall, this command is used to perform a restore operation using ASR, where a source disk image is restored to a target volume, erasing any existing data on the target volume.
