This is a script that locks your computer!

Type in the console:

edit startup

and type this code:

local funtion clearScreen()
term.clear()
term.setCursorPos(1,1)
end
while true do
clearScreen()
print("Welcome at ««YOUR NAME»» computer")
write"Password: "
if read("*") == "««PASSWORD»»" then
print("Correct password!")
sleep(1)
clearScreen()
shell.run("shell")
else
print("Incorrect password!")
sleep(2)
os.shutdown()
end
end

NOTE: You have to change ««YOUR NAME»» in your username and««PASSWORD»» into your password.

Do anybody know how I can exit a program to the terminal

you can easily bypass it by using ctrl + t.

That only works though if you call that from within the main program's scope, outside of any functions.
Or else your function will just return back to your main program.

If you're not planning on doing any exception handling in the future, then you could use a quick'n'dirty method and just throw an error wherever you want to exit your program:

function one( someVariable )
  -- Do something
  if someConditionIsMet then
	error("Program stopped ;-)")
  end
end

-- Main loop
while true do
  -- Do something
  one( someVariable )
end

gosh, took me way to long to spot the typo at the top where it says "funtion" instead of "function"

else
print("Incorrect password!")
sleep(2)
clearScreen()
sleep(4)
os.reboot()
end
end

I changed the end to this to make it reboot with a short delay instead of shutdown.

I suggest adding os.pullEvent = os.pullEventRaw to the first line of your code to prevent termination. Other than that it looks like you are off to a good start with Lua!
