Message of the day
Many computer systems display a message of the day or welcome message when a user first connects to them, logs in to them, or starts them. It is a way of sending a common message to all users, and may include information about system changes, system availability, and so on. More recently, systems have displayed personalized messages of the day.
On many time-sharing systems, the contents of the message of the day are fetched from a system file:
- Compatible Time-Sharing System;[1]
- Multics: the motd info segment;[2][3]
- TOPS-10[3]
- Incompatible Timesharing System (ITS)[3]
- Unix-like systems: the /etc/motd file, though most modern Linux distributions do not support the /etc/motd file.[citation needed]
- Univac VS/9[4]
- CP/CMS[5]
Usage
The contents of the special file are displayed after the user logs in successfully, typically before the login shell is started.[6]
Newer Unix-like systems may generate the message dynamically when the host boots or a user logs in.[7]
Various server-based PC games display messages of the day, including Half-Life, Call of Duty, Minecraft, and Battlefield. They may be personalized, encouraging users to try new features or make in-game purchases.[8]
Some IRC servers also display a message of the day on login.[9]
