Get the name of the internal boot volume

Hi,
I’m booting from an external drive but would like to get the name of the Mac’s internal boot volume (eg “MacintoshHD”).
Do you know a quick command? (if possible in 1 order)
Thanks

Try this with Shell.Execute:

diskutil info -plist "$(bless --getBoot)" | plutil -extract VolumeName raw -- -

You win ! thanks
