Start a new shell as root

Opens a new shell as root. Useful if you want to run a lot of commands as superuser without needing to sudo each of them.

sudo -i

Why exactly is that safer?

Comment by fabsh 379 weeks and 6 days ago
sudo -s

is the equivalent of

sudo su


sudo -i

is the (recommended) equivalent of

sudo su -

A "-u" switch can also be used, so

sudo -i -u foo

is equivalent to

sudo su - foo

@fabsh: it's not safer so to say, but `sudo -i`will give you root's environment (like `sudo su -`) while `sudo su` (or `sudo -s`) won't.

Comment by raphink 379 weeks and 6 days ago

And, if you think about it, what you really want is to run a shell as root. If you do sudo sh it may make sense, but that will disregard the users's default shell. There is no point in running 'su' as root just to get a shell. So, sudo -i or sudo -s, pretty please.

@raphink OK. So by environment you mean home directory and shell presets, I presume? :)
