  • 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 Show Sample Output

    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"

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.
