[Linux-disciples] Making sudo portable

[Stephen R Laniel]

I've been writing my scripts nowadays to be more portable,
for instance using '${HOME}' rather than '~' or
'/home/slaniel', using 'if [ ... ]' blocks specific to the
different OSes I run them on, etc.

But I just noticed one place where portability seems hard to
come by: sudo. I'd like to be able to say,

if( ${USER} is a sudoer ) {
	some stuff;
}
else {
	echo Some error;
}

The reason I would like this is that I have a script that
runs 'sudo apt-get upgrade', and I just now accidentally ran
it on a machine where I don't have sudoer privileges.

Is there any kind of portable isASudoer() function?
