What's this?

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

Application network trace based on application name
This command takes an application name as an argument and then it will listen to the tcp traffic and capture packets matching the process Id of the application. The output shows: local address / local port / Remote Address / Remote port / State / Owning Process ID

Remotely sniff traffic and pass to snort
I have a small embedded linux device that I wanted to use for sniffing my external network, but I didn't want to recompile/cross-compile snort for the embedded platform. So I used tcpdump over ssh to pass all the traffic as pcap data to a "normal" Linux system that then takes the pcap data and passes it to snort for processing.

random git-commit message
Do a git commit using a random message.

Update Ping.fm status
Updates your Ping.fm status and websites supported by ping.fm (like twitter, facebook, and google talk).

Monitor iptables in realtime

Merges given files line by line
In the above example all files have 4 lines. In "file1" consecutive lines are: "num, 1, 2, 3", in "file2": "name, Jack, Jim, Frank" and in "file3": "scores, 1300, 1100, 980". This one liner can save considerate ammount of time when you're trying to process serious portions of data. "-d" option allows one to set series of characters to be used as separators between data originating from given files.

Extract tarball from internet without local saving

list files recursively by size

Get absolut path to your bash-script
Another way of doing it that's a bit clearer. I'm a fan of readable code.

Rename duplicates from MusicBrainz Picard
Renames duplicates from MusicBrainz Picard, so you get the latest copy and not a bunch of duplicates.
