Root/Administrator privileges from cygwin terminal

A while ago, I researched a Cygwin equivalent for sudo but that's what
I ended up doing, myself.

I use something similar:  [[ $(groups) == *Administrators* ]]
It's more readable and it works on pretty much every version of Bash.

For POSIX compatibility, you could probably use something like:
case $(groups) in
  *Administrators*) echo Member of Administrators group;;
  *) echo Not a member of Administrators group;;
esac

This approach has worked well enough for me in the past but I don't do
anything too unusual other than stopping / starting Windows services.
