Installation

Copy contents of virtualbox-bash-completion.sh to ~/.bash_completion
open new terminal and try auto completion !

Usage

vmname, snapshot-name completion can start with " character.

bash$ vboxmanage showvminfo "[tab]
"Plan 9"        "Window-10"     "node-2"        
"Ubuntu-20.10"  "node-1"        "node-3" 

bash$ vboxmanage showvminfo "Ub[tab]

bash$ vboxmanage showvminfo "Ubuntu-20.10"

bash$ vboxmanage showvminfo [tab]
1) "node-1"        3) "node-3"        5) "Ubuntu-20.10"  
2) "node-2"        4) "Plan 9"        6) "Window-10"

bash$ vboxmanage showvminfo 5[tab]

bash$ vboxmanage showvminfo "Ubuntu-20.10"

Names that end with capital N should replace with [0-9] number for completion works.

bash$ vboxmanage controlvm "node-1" nic[tab]
nicN           nicpromiscN    nicpropertyN   nictraceN      nictracefileN  

bash$ vboxmanage controlvm "node-1" nic2 [tab] 
bridged     generic     hostonly    intnet      nat         natnetwork  null

bash$ vboxmanage modifyvm "node-1" --nic[tab]
--nic-bandwidth-groupN  --nic-propertyN         --nic-typeN
--nic-boot-prioN        --nic-speedN            --nicN
. . .
# options also can use "=" character like --nic2=[tab]
bash$ vboxmanage modifyvm "node-1" --nic2 [tab]
bridged      generic      hostonlynet  nat          none         
cloud        hostonly     intnet       natnetwork   null
