====== Log In And Switch Users In Multiuser Targets ======

**General Information**

Targets are the new "runlevels" equivalent if you are coming from RHEL 6. You need to be able to switch users.

----

View default target (target at boot)
<code bash>
~$ systemctl get-default
multi-user.target
</code>

\\
Switch User
<code bash>
su - <username>
</code>
  * -, -l, --login => Load login profile (~/.bash_profile)
  * When no username is specified after options (such as -), root is assumed
  * **Always use a login shell when switching users (su -)**.

\\
Types of profiles
  * ~/.bash_profile => Execute upon login shells
  * ~/.bashrc => Execute on every shell
  * /etc/profile => Executed on every user login (system wide environmentals)
  * /etc/bashrc => Executed on every user interactive shell (system wide functions and aliases)
