sendmsg(1) 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:

a local user or a sendfile alias (see below), e.g.: framstag
[email protected]
an user on a remote host, e.g.: [email protected]
like above, but in URL-syntax, e.g.: saft://
like above, but with alternate SAFT-port, e.g.: saft://


-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.
Verbose mode: show SAFT protocol messages.
Show version information and exit.
Force sending of messages and ignore tty (re)settings.
Reply to last received message.
Receive messages only on this tty. This is the default.
Allow receiving messages on other ttys.
Allow sending of multiline messages messages.
-s 'message'
Send directly message.
-u 'from'
Set sender to from instead of $LOGNAME.
Quiet mode: print no transfer messages.
