[$] Sudo and its alternatives

Sudo is a ubiquitous tool for running
commands
with the privileges of another user on Unix-like operating systems. Over
the past decade or so,
some alternatives have
been developed; the base system of OpenBSD now comes with doas instead, sudo-rs is a subset of
sudo reimplemented in Rust, and, somewhat surprisingly, Microsoft also
recently announced
its own Sudo for Windows. Each of these offers a different approach to the
task of providing limited privileges to unprivileged users.
