It just seems strange to me that the same command (even if unlikely

different distros.
Single quotes would get the root shell path, double would get the
executing users path and has nothing to do w/ sudo (as jack noted).
But as I mentioned, with single quotes (as in the subject header) some
distros return the user's path, others return root's path. Even if it's
a command that shouldn't be counted on, I was surprised to see a
difference between distros. My test system has room for 7 different
distros, so I'm learning about other ways to do things in Linux than
"the Mandriva way".
Sudo by default filters most/all environment variables, because it can
be a huge security risk. Massively so if you have a multiuser system
which uses restricted sudo to allow users to perform specific tasks
(vs a single-user system like an ubuntu desktop which uses sudo to
raise privs of the single owner)
That answers another question I was going to ask someday, why some
distros allow an unprivileged user to "poweroff" but others require
privileges. Thanks!
