vboxmanage:tldr:7d8ab

This command is a command-line instruction for the VirtualBox software to start a specific virtual machine (VM) with the name stored in the variable select.

Here is a breakdown of the components of this command:

• VBoxManage: This is the command-line tool used to manage VirtualBox virtual machines. It allows you to control and configure various aspects of your VMs.
• startvm: This is a subcommand of VBoxManage used to start a virtual machine.
• ${select}: This is a placeholder or variable in some scripting languages (e.g., bash) that will be replaced with the actual name of the virtual machine to start. The ${} syntax signals the use of a variable.

To use this command, you need to replace ${select} with the name of the specific VM you want to start. For example, if the name of the VM is "MyVM," the command would be:

VBoxManage startvm MyVM

Executing this command will initiate the start process for the specified virtual machine, and it will begin running.
