List all TCP opened ports on localhost in LISTEN mode

Alternative of OJM snippet :

This one show the IP too, where ports bind. It's very important, because if there's only 127.0.0.1 instead of 0.0.0.0, connections from internet are rejected.

Show apps that use internet connection at the moment. (Multi-Language)

Show apps that use internet connection at the moment.

Can be used to discover what programms create internet traffic. Skip the part after awk to get more details, though it will not work showing only unique processes.

This version will work with other languages such as Spanish and Portuguese, if the word for "ESTABLISHED" still contain the fragment "STAB"(e.g. "ESTABELECIDO")

Monitor Applications application that are connected/new connections

The -p parameter tell the netstat to display the PID and name of the program to which each socket belongs or in digestible terms list the program using the net.Hope you know what pipe symbol means!

Presently we wish to only moniter tcp connections so we ask grep to scan for string tcp, now from the op of grep tcp we further scan for regular expression /[a-z]*.

Wonder what that means ?

If we look at the op of netstat -p we can see that the name of the application is preceded by a / ( try netstat -p ) so,now i assume application name contains only characters a to z (usually this is the case) hope now it makes some sense.Regular expression /[a-z]* means to scan a string that start with a / and contains zero or more characters from the range a-z !!. Foof .. is t

Kill a daemon by name, not by PID

Just find out the daemon with $ netstat -atulpe. Then type in his name and he gets the SIGTERM.
