How to find whether the user is sudo or dzdo user in commandline?

Question

I've systems with dzdo and sudo users, Its necessary to find the user who is sudo/dzdo to run the following commands accordingly. like updating ca-certificates, changing permission ..etc

  if [ -f /usr/bin/dzdo ]; then

    /usr/bin/dzdo "$@"

  else

    /usr/bin/sudo "$@"

Above won't be applicable for users who have a dzdo but using sudo.
