prints the list of active users on a remote host.

## NAME

who@ - prints the list of active users on a remote host.

## SYNOPSIS

**who@** \[ *host* \]

## DESCRIPTION

**who@** connects to TCP port 11 (Systat) on *host* and prints any data it receives. It removes CR (\\015) and converts unprintable characters to a visible format.

If *host* is not supplied, **who@** connects to the local host.

Some computers respond to port 11 with a list of active users. For example, they may be running
