examples

connect to localhost with default credentials and attach to a new temp queue on exchange "default":

./konsum

Connect to a host with TLS on a custom port, authenticating with SSL client certificate. On every received message a callback is spawned. The message will be ACKed when the callback exits successfully. First 500 bytes of the message body are printed to stdout. Header infos are always printed to stdout:

konsum -o amqp.example.com -p 5673 -T -k amqp-key.pem -c amqp-crt.pem -y vhost -x exchange -X./callback.sh -a -c -a callback.config.sh -f 2 -r routing.key.# -l 500

Authenticate with user and pass. Generate a file for every message:

konsum -o amqp.example.com -U user -P pass -q queue -t

Provide a custom CA cert for proving the server's identity via enviroment:

$ env SYSTEM_CERTIFICATE_PATH=/etc/amqp/cacert.crt ./konsum -T -y vhost -x exchange

Stop with ^C

If INPUTFILE is a file, the file is sent as a message and the program exits. If INPUTFILE is a directory, the directory is watched via inotify and every file, which is written and closed or moved in gets sent, optionally only files which match one or several SUFFIXes. Optionally the file name is written into a message header named HEADERNAME. Optionally Content-Type and Content-Encoding headers are set via magic retrieved from file contents.

Line-by-line mode sends one message per INPUTFILE line.

examples

Send a message containing a file and put the filename into a fileName message header:

agitprop -x amq.topic -r test -F fileName -f agitprop.hs
