Discussion

Unfortunately, sudo is not installed by default on every system. It is usually installed on Linux and OpenBSD; other systems will vary. You should consult your system documentation and install it if it's not already there.

WARNING

You should always use visudo to edit your /etc/sudoers file. Like vipw, visudo locks the file so that only one person can edit it at a time, and it performs some syntax sanity checks before replacing the production file so that you don't accidentally lock yourself out of your system.
