=head1 NAME
sendxmpp - send xmpp messages from the commandline.
=head1 SYNOPSIS
sendxmpp [options] <recipient1> [<recipient2> ...]
sendxmpp --raw [options]
=head1 DESCRIPTION
sendxmpp is a program to send XMPP (Jabber) messages from the commandline, not
unlike L<mail(1)>. Messages can be sent both to individual recipients and chatrooms.
=head1 OPTIONS
=over
=item B<-f>,B<--file> I<file>
Use I<file> configuration file instead of F<~/.sendxmpprc>
=item B<-u>,B<--username> I<user>
Use I<user> instead of the one in the configuration file
=item B<-p>,B<--password> I<password>
Use I<password> instead of the one in the configuration file
=item B<-j>,B<--jserver> I<server>
Use jabber I<server> instead of the one in the configuration file.
=item B<-o>,B<--component> I<componentname>
Use componentname in connect call. Seems needed for Google talk.
=item B<-r>,B<--resource> I<res>
Use resource I<res> for the sender [default: 'sendxmpp']; when sending to a chatroom, this determines the 'alias'
=item B<-t>,B<--tls>
Connect securely, using TLS
=item B<-e>,B<--ssl>
Connect securely, using SSL
=item B<-n>,B<--no-tls-verify>
Deactivate the verification of SSL certificates. Better way is to use parameter B<--tls-ca-path> with the needed path to CA certificates.
=item B<-a>,B<--tls-ca-path>
Path to your custom CA certificates, so you can verificate SSL certificates during connecting.
=item B<-l>,B<--headline>
Backward compatibility option. You should use B<--message-type=headline> instead. Send a headline type message (not stored in offline messages)
=item B<--messages-type>
Set type of message. Supported types are: B<message chat headline>. Default message type is B<message>. Headline type message can be set also with B<--headline> option, see B<--headline>
=item B<-c>,B<--chatroom>
Send the message to a chatroom
=item B<-s>,B<--subject> I<subject>
Set the subject for the message to I<subject> [default: '']; when sending to a chatroom, this will set the subject for the chatroom
=item B<-m>,B<--message> I<message>
Read the message from I<message> (a file) instead of stdin
=item B<-i>,B<--interactive>
Work in interactive mode, reading lines from stdin and sending the one-at-time
=item B<-w>,B<--raw>
Send raw XML message to jabber server
=item B<-v>,B<--verbose>
Give verbose output about what is happening
=item B<-h>,B<--help>,B<--usage>
Show a 'Usage' message
=item B<-d>,B<--debug>
Show debugging info while running. B<WARNING>: This will include passwords etc. so be careful with the output!
=back
=head1 CONFIGURATION FILE
You may define a 'F<~/.sendxmpprc>' file with the necessary data for your
xmpp-account, with a line of the format:
=over
I<user>@I<server> I<password> I<componentname>
=back
e.g.:
# my account
alice@jabber.org secret
('#' and newlines are allowed like in shellscripts). You can add a I<host> (or IP address) if it is different from the I<server> part of your JID:
# account with specific connection host
alice@myjabberserver.com;foo.com secret
You can also add a I<port> if it is not the standard XMPP port:
# account with weird port number
alice@myjabberserver.com:1234 secret
Of course, you may also mix the two:
# account with a specific host and port
alice@myjabberserver.com;foo.com:1234 secret
B<NOTE>: for your security, sendxmpp demands that the configuration
file is owned by you and readable only to you (permissions 600).
=head1 EXAMPLE
$ echo "hello bob!" | sendxmpp -s hello someone@jabber.org
or to send to a chatroom:
$ echo "Dinner Time" | sendxmpp -r TheCook --chatroom test2@conference.jabber.org
or to send your system logs somewhere, as new lines appear:
$ tail -f /var/log/syslog | sendxmpp -i sysadmin@myjabberserver.com
NOTE: be careful not the overload public jabber services
