Comparing UNIX networking commands : netstat, lsof and ss

I've realized recently there's a lot more availability in UNIX commands to look at your network (open ports, etc...).

Some sample commands that do the same thing, which I'll investigate later :

netstat -a -p  | grep 13100

ss -all | grep 13100

lsof -n -i4TCP | grep 13100

These three commands do a lot of similar things, albeit with some minor tweaks; and then pipe it to grep to look at a specific port.

Currently, my favorite for information and formatting is lsof.

I'll write more later...
