Bug#935504: grub: update-grub doesn't recognise short option -v

[Aaron Schaal]

Source: grub
Version: 2.02+dfsg1-20
Severity: minor

Dear Maintainer,

On my system, the command 'update-grub -v' yields an error message "unknown option »-v«". It also prints a list of the possible options for update-grub, including the option -v.
The long version "update-grub --version", however, works as expected. To me, this seems to be a very small bug. 

Regards,
Aaron
