umq [-hV]
-h, --help display this message
-V, --version output version
Push a message to a host with port
$ umq push <host> <port>
Receive a message on a host with port
$ umq recv <host> <port>
Display help on a command
$ umq help push
$ echo "hello world" | umq push localhost 3000
$ umq recv localhost 3000 | { \
while read line; do \
echo "msg: $line"; \
done; \
}Listening on localhost can be achieved by simple providing a port:
$ umq recv 3000 | { \
while read -r line; do \
echo "got: '$line'"; \
done; \
}This will create a server and listen on localhost port 3000 for all
incoming tcp messages.
You can connect and read from the server by using umq recv with a host
and port:
$ umq recv localhost 3000
Pushing data to a umq receiver can be performed via umq push:
$ echo "ping" | umq push localhost 3000
This should yield the following response on the server:
got: 'ping'
When multiple peers are connected via umq recv <host> <port> to a single
umq receiver, messages are emitted to each peer via the RR (Round-Robin)
