If you're running bash, then giving the full path for sudo will
circumvent any aliases you've defined, and any other versions
of sudo available from earlier in your $PATH, but there's not
necessarily any security bonus. After Greg (2018):
$ function /usr/bin/sudo { echo teehee; }
$ /usr/bin/sudo whatever
teehee
$
Cheers,
