Thread: Can someone please explain this code?

code:

sudo su  xhost +si:localuser:lightdm  sudo su lightdm -s /bin/bash  gsettings set com.canonical.unity-greeter background '/usr/share/backgrounds/awesome_.png'  exit

i came across here linked tothis
haven't used sudo su before , of rest of code seems complicated well.

using

code:

sudo su

uses root priviledges (sudo) switch users (su) , without argument defaults superuser (root). if needed access files user "smith" has access use:

code:

su smith

need smith's password. in case, using "su" work too, if knew root password. effect, acting user, lasts until issue command: exit, or close terminal.

i'm not sure xhost does, doing somethign related lightdm user.

"sudo su lightdm" switches user lightdm, , sets default shell bash.

gsettings line looks changing background of login screen.

there should exit @ end. 1 exit leave open terminal logged in root.
