What's the sudo equivalent for FreeBSD?

Question

In pretty much any GNU/Linux distribution you use sudo or su, What's the right choice for FreeBSD 10 ?

Answer 1

FreeBSD does support sudo it's likely just not installed by default. Installation instructions are here, titled: FreeBSD: Install sudo Command To Execute A Command As The Root.

As root:

FreeBSD < 10

# pkg_add -r sudo

FreeBSD 10+

# pkg install sudo

The default sudoers file is located here: /usr/local/etc/sudoers. To edit it and add rules you need to use the visudo command.

$ su -
$ visudo

Then to give a user access to everything as root:

userX ALL=(ALL) ALL

To become root (as userX):

$ sudo -s
-or-
$ sudo -i
