I’d like to run multiple linux commands using azurerm_virtual_machine_extension. Is there a sophisticated way to use multiple commands side by side instead of listing them in a single line? I’ve previously used it as below.

resource "azurerm_virtual_machine_extension" "run_command" {
  for_each             = var.vm_template
  name                 = "${each.value.vm_name}-run_command"
  virtual_machine_id   = azurerm_linux_virtual_machine.vm[each.key].id
  publisher            = "Microsoft.Azure.Extensions"
  type                 = "CustomScript"
  type_handler_version = "2.0"
  timeouts {
    create = "1h" # VM 개수가 많으면 그만큼 더 오래걸림
  }
  settings = <<SETTINGS
 {
  "commandToExecute": "bash -c 'hostnamectl set-hostname --static ${each.value.hostname}'&& sleep 60 && sh /tmp/for_image.sh > /tmp/installed.log 2>&1"
 }
SETTINGS
}

Is it possible to write a code by aligning it line by line without executing all the commands line like above? I need your help.
