[SOLVED] Shell Script: How i can list trough cli of virtualbox the vms and delete all but one called "SaveThisOne"?

Issue

Shell Script: How i can list trough cli of virtualbox the vms and delete all but one called "SaveThisOne"?

CAUTION: The lines below deletes all virtualbox vms:

class="lang-bash prettyprint-override">VBoxManage list runningvms | awk '{print $2;}' | xargs -I vmid VBoxManage controlvm vmid poweroff
VBoxManage list vms | awk '{print $2;}' | xargs -I vmid VBoxManage unregistervm --delete vmid

Possible solution, after the help of the guys here, pmf, BeatOne and tripleee what i did was:

#!/bin/bash
#This script list all VM's through virtualbox cli, vboxmanage, do poweroff and deletes the virtual machines case they don't are listed in $vmnames variable.
# list all VM's
vboxmanage list vms |
awk -F '"' '{print $2}' |
while read -r vmnames; do
    case $vmnames in
      "Win10" | "Ubuntu" | "YourVMNameToSave" ) continue;; 
    esac 
    # poweroff and delete case name is not listed in $vmnames variable as a string. 
    vboxmanage controlvm "$vmnames" poweroff
    vboxmanage unregistervm "$vmnames"  --delete
done

Solution

i think the output of vmboxmanage list vms looks like this:

"SaveThisOne" {asdgfdasg}
"DeleteThis" {asdfasdfasdg}
"AndThis" {gasdfas}
"AndThisToo" {asdfas}

Here is an Example:

#!/bin/bash

# list all VMs
vms=$(vboxmanage list vms)

# Check every vm
while read -r line; do
    # Get VM name
    vm_name=$(echo "$line" | awk -F'"' '{print $2}')
    echo $vm_name

    # check name and delete
    if [ "$vm_name" != "SaveThisOne" ]; then
        # delete if name not like 
        vboxmanage unregistervm "$vm_name" --delete
    fi
done <<< "$vms"

i think that should do the job, but i have not tested it, so be careful
