Just an idea: Could the default background color of the Cygwin console
be changed from black to grey (or RED) if the terminal has been
started with Administrator rights?
Assuming that:
1. The Administrators group is called "Administrators"
2. There aren't any non-administrative groups with "Administrators" in the
name
3. You're using mintty for your terminal
You can run the following in bash or zsh with the desired RGB values:
if [[ `id -Gn` == *Administrators* ]]
then
echo -ne "\e]11;#FFBBEE\a";
fi
Looking at the output of /usr/bin/id -a was my first guess too. But
this fails quickly because the names are localized. Seriously MS runs
the Windows group names through the l10n wringer!! So what works on
Windows for Germany will surely fail for Windows for Japan. Thus I am
looking for a more portable solution.
Maybe the numeric group ids are more 'portable' across the Windows
versions for different countries?
Admin group is always Windows SID 1-5-32-544 and gid 544 in Cygwin,
unless somebody overloads the gid values via an /etc/group file.
If you want to be really sure, you have to check every numeric gid
returned by `id -G' if it resolves to SID 1-5-32-544. You can do
this with the getent(1) tool.
Fortunately getent allows multiple keys, so this works:
case "$(getent group $(id -G))" in
*:S-1-5-32-544:*) echo admin ;;
esac
Unfortunately this may be is slow in domains due to unneeded AD
requests. Unlike mkgroup, getent output cannot be restricted to local
groups (and the '-s SERVICE' option is apparently a no-op).
