sendmsg - send a message via Internet
sendmsg [ −46vVfrmMl ] [ −u ’from’ ] [ −s ’message’ ] recipient
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 AT bofh DOT belwue DOT 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
|
-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. |
