There is 1 alternative - vote for the best!

Terminal - Alternatives
port=8888;pid=$(lsof -Pan -i tcp -i udp | grep ":$port"|tr -s " " | cut -d" " -f2); ps -Afe|grep "$pid"|grep --invert-match grep | sed "s/^\([^ ]*[ ]*\)\{7\}\(.*\)$/\2/g"

A way not so simple but functional for print the command for the process that's listening a specific port.

I got the pid from lsof because I think it's more portable but can be used netstat

netstat -tlnp

Know a better way?

If you can do better, submit your command here.

What others think

I don't have Ubuntu to hand, but I'm sure you mean /proc, not /etc.

Also, this won't for things like apache, where several processes all claim to listen to the same port. For that you'd have to turn the list of pids into something like {pid1,pid2,pid3}, or use head to get the first match.
