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@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
- -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.
- -V
- Show version information and exit.
- -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.
- -l
- Allow sending of multiline messages messages.
- -s 'message'
- Send directly message.
- -u 'from'
- Set sender to from instead of $LOGNAME.
- -q
- Quiet mode: print no transfer messages.
