What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

Universal configuration monitoring and system of record for IT.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Show which programs are listening on TCP and UDP ports

-p Tell me the name of the program and it's PID

-l that is listening

-u on a UDP port.

-n Give me numeric IP addresses (don't resolve them)

-t oh, also TCP ports

Know a better way?

If you can do better, submit your command here.

What others think

really nice, but in Ubuntu you must use 'sudo' before that command if you wish to see the pids. :)

You can see names and PIDs of the processes you own.

From the man page...

PID/Program name:

Slash-separated pair of the process id (PID) and process name of the process that owns the socket.... You will also need superuser privileges to see this information on sockets you don?t own.
