Lock and unlock the screen from command line

Question
Is there a way to lock/unlock the screen from a script?

Answer
The answer is “yes”. Lock the screen:

gnome-screensaver-command -l

Unlock the screen:

gnome-screensaver-command -d

Demo (lock the screen, then unlock it in 5 seconds):

gnome-screensaver-command -l && sleep 5 && gnome-screensaver-command -d
