leave

Leave is a command-line tool used in Unix-like operating systems to terminate a user's session by gracefully logging them out. It is commonly used as a simple form of logout or to indicate that the user will be away from their computer. When executed, the leave command displays a message with the current time and specifies the time when the user is expected to return. The user's shell is then terminated. Additionally, the leave command can accept an argument in the format [+hhmm] to specify the duration of absence. If no return time is provided, leave exits immediately. The leave command is often used as a polite way to inform others that the user is temporarily unavailable. It is a convenient tool for managing time and organizing work by defining breaks or periods of absence. However, it should be noted that the leave command may not be available on all systems or distributions.
