SENDMSG(1)

NAME
sendmsg - send a message via Internet

SYNOPSIS
sendmsg [ -46vfrmM ] [ -s 'message' ] recipient

DESCRIPTION
sendmsg sends a one line text message to the terminal(s) of the specified recipient.

On the receiving site there must be a SAFT-server (Simple Asynchronous File Transfer) installed, like the sendfiled and the recipients terminal must be writeable. The recipient address can be specified as:

user
    a local user or a sendfile alias (see below), e.g.: framstag

user@host
    an user on a remote host, e.g.: framstag@bofh.belwue.de

saft://host/user
    like above, but in URL-syntax, e.g.: saft://bofh.belwue.de/framstag

saft://host:port/user
    like above, but with alternate SAFT-port, e.g.: saft://bofh.belwue.de:4870/framstag

OPTIONS

-4, -6
    Explicitly force IPv4 or IPv6 connections. By default, the program will try to resolve the name given, and choose the appropriate protocol automatically. If resolving a host name returns both IPv4 and IPv6 addresses, sendmsg will try to use the adresses in the order they are returned by the resolver.

-v  Verbose mode: show SAFT protocol messages

-f  Force sending of messages and ignore tty (re)settings.

-r  Reply to last received message.

-m  Receive messages only on this tty. This is the default.

-M  Allow receiving messages on other ttys.

-s 'message'
    Send directly message

EXAMPLES
sendmsg neg@linux.rus.uni-stuttgart.de
message: how about lunch?
