# zshutdown\_notify(8)

notify users of impending shutdown via Zephyr

## NAME

zshutdown\_notify - notify users of impending shutdown via Zephyr

## SYNOPSIS

**zshutdown\_notify**

## DESCRIPTION

*zshutdown\_notify* reads the standard input until EOF is reached, and then sends a Zephyr notice with the official hostname, the collected input, and a warning message as the message body of the notice. The notice is sent to class FILSRV, instance  *\<hostname\>,* recipient "\*", where \<hostname\> is the official hostname of the sending host.

Any users who are using resources on the sending host are expected to subscribe to these messages so they will be warned of any impending shutdowns.

*zshutdown\_notify* is usually invoked from within */etc/shutdown.*
