Users

Unix-like systems (like the one you're using) support multiple users. Each user has their own home directory, their own files, and their own permissions.

If you're like most people these days, you're the only user on your machine. It used to be more common for multiple people to share a single computer, or for multiple people to do their work on the same computer over a network.

Sudo

The sudo keyword lets you run a command as the root "superuser".

Some people are pedantic and pronounce sudo as "sue-doo." Others are correct and pronounce it "sue-dough."

It's short for "superuser do". To use it, you'll need the password of an account with superuser privileges, which you should already have if you're the only user of your machine.

sudo grants unrestricted access and can risk system damage if you don't know what you're doing. All commands in this course are safe, but other commands should be reviewed before running with sudo.
