Proxmox VM & Disk Script

pve_delete_vm.sh

#!/bin/bash

# Script to delete a Proxmox VM and all associated hard disks.
# Usage:
#   ./delete_vm_with_disks.sh <vmid>         - Deletes the specified VM after user confirmation.
#   ./delete_vm_with_disks.sh <vmid> --force - Force deletes the specified VM without confirmation.
#
# Arguments:
#   <vmid>  : The ID of the Proxmox VM to delete.
#   --force : Optional argument to skip the confirmation prompt.
#
# Note: The script will identify and delete all disks associated with the VM
#       from the Proxmox storage.
#
# Example:
#   ./delete_vm_with_disks.sh 100            - Deletes VM with ID 100 after user confirmation.
#   ./delete_vm_with_disks.sh 100 --force    - Force deletes VM with ID 100.
