How can I remove a carriage return, add a time stamp and ignore some data from a live MQTT feed

I type mosquitto_sub -d -t +/# from the Ubuntu terminal to access the MQTT stream.

Real output from the live MQTT stream is this:

Sending PINGREQ

There is no way of predicting when the next PUBLISH will be seen as they are only seen in the stream when the vehicle has transmission/reception from the GSM/3G towers

To filter I add mosquitto_sub -d -t +/# 2> >(grep PUBLISH) this will only allow lines with PUBLISH in it, hence the ouput is:

How would I be able to eliminate a few of the fields and also add a time stamp everytime I receive something; I 've tried using sed but had no luck. I entered $ mosquitto_sub -d -t +/# 2< <(grep PUBLISH) 2< <(sed "s/^/ date/") , $ mosquitto_sub -d -t +/# 2< <(grep PUBLISH) 2< <(sed "s/^/$date`/")

Q: How can I change my input to the terminal so that the output from the above live feed would be:

'm/gf/TMX6BP/075/d/status', 86,637999,164563,-33.836465,151.051189,[timestamp]

Possible solutions (future referencing):

Using the mosquitto_sub -d -t +/# 2> >(sed -n "s|.*\('.*',\).*|\1|p") | sed "N;s/\n/ /;s/$/ $(date)/" The output is:

Using the mosquitto_sub -d -t +/# 2> >(grep PUBLISH) | sed "N;s/\n/ /;s/$/ $(date)/" command from the terminal the output is

Using the mosquitto_sub -d -t +/# 2>&1 | sed -n "/PUBLISH/{s|.*\('.*',\).*|\1|;N;s/\n/ /;s/$/ $(date)/;p}" The output is
