I just came up with this recipe to change the default PS1 value to use red for the user AT host part of the prompt and to change the $ character to a #:

    if id | grep -qi 'member of administrators group'
    then
        export PS1=$(echo "$PS1" | sed -e 's_32_31_' -e 's_\\\$_#_')
    fi

I’m not certain the string match on the output of id(1) works everywhere.  Is there a better way to check for admin privileges under Cygwin?  You can’t check for UID or EUID == 0, for example, as you’d do on a true POSIX system.

Perhaps something like this should go into the default /etc/profile?
