OsConsoleCommand

In addition, one can further restrict this function to only certain administrators/gods. See Threat level for more information on how to do this.

If the script owner does have the necessary permissions to call this function, then they can do anything someone with direct access to the command console could do, such as changing the avatar passwords, deleting sims, changing the terrain, etc.

This command represents the highest security threat of any OSSL function, giving it a threat level of Severe.

Do not use or allow this function unless you are absolutely sure of what you're doing!

default
{
  touch_start(integer num_detected)
  {
    osConsoleCommand("login disable");
    llSay(0, "Logins are disabled");
  }
}

This would issue a Login Disable command on the console to prevent logins.
