update-motd(8)
NAME
update-motd - Automatically update the message-of-the-day (MOTD)
SYNOPSIS
update-motd
DESCRIPTION
update-motd is a daemon that will dynamically generate and update
/etc/motd according to the output of scripts installed by the administrator.
When update-motd initially starts, it will run all scripts in /etc/update-motd.d, /etc/update-motd.d/hourly, /etc/updatemotd.d/daily, /etc/update-motd.d/weekly, and /etc/updatemotd.d/monthly, concatenating the output and writing this to /etc/motd.
Thereafter, update-motd will sleep, and awake every 10 minutes, and rerun all of /etc/update-motd.d/* again. Additionally, every 60 minutes, it will run /etc/update-motd.d/hourly/*. And every 24 hours, it will also run /etc/update-motd.d/daily/*. Every 7 days, it will run /etc/update-motd.d/weekly/*. And every 30 days, it will run /etc/update-motd.d/monthly/*.
Note that these time intervals are relative to when the update-motd
daemon starts, and not to the current system time.
