pub is an executable for piping data from stdin to a specified Redis pub/sub channel.

A typical use for this tool is to tail a log file, match a specific line with grep, and pipe it into Redis where multiple consumers can do something different with each incoming log line:

tail -F /var/log/somelogfile.log | grep "tracker.gps.parsed" | pub loglines

It also comes with a utility named sub for piping from a Redis pub/sub channel to stdout:

sub loglines | grep "somemsg"
