Source: https://apple.stackexchange.com/a/126762
Login as that user eg. sudo su - username
Ask for confirmation:
[bash]
osascript -e ‘tell app "System Events" to log out’`
[/bash]
Just do it:
[bash]
osascript -e ‘tell app "System Events" to «event aevtrlgo»’
osascript -e ‘tell application "loginwindow" to «event aevtrlgo»’
[/bash]
Yes, the symbols « and » are correct.
