I would like sudo to always do as if I had passed the -A (--askpass) option.
I would like that so that sudo always uses my gnupg agent and password store. It already works if I pass -A manually, but I would like -A to always be passed.
Would an alias be enough? You can go to your $HOME/.bashrc file and bellow other existing alias you can enter
alias sudo='sudo -A'
I have similar customized alias in my .bashrc file that work fine.
Before to make it permanent, you can try it in your shell to verify that works ok.
