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/
You can sign-in using OpenID credentials, or register a traditional username and password.
First-time OpenID users will be automatically assigned a username which can be changed after signing in.
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.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

This solution is similar to  except that it does not have any dependency on GNU Parallel. Also, it tries to minimize the impact on the running system (using ionice and nice).
make usable on OSX with filenames containing spaces. note: will still break if filenames contain newlines... possible, but who does that?!
Why use many different utilities all piped together, when you only need two?
Output contains also garbage (text parts from netstat's output) but it's good enough for quick check who's overloading your server.
I have found that base64 encoded webshells and the like contain lots of data but hardly any newlines due to the formatting of their payloads. Checking the "width" will not catch everything, but then again, this is a fuzzy problem that relies on broad generalizations and heuristics that are never going to be perfect.
What I have done is set an arbitrary threshold (200 for example) and compare the values that are produced by this script, only displaying those above the threshold. One webshell I tested this on scored 5000+ so I know it works for at least one piece of malware.
Usefull if you only want to see the package names, or if you want to use them in a script.
On the Mac, the 'ls' function can sort based on month/day/time, but seems to lack ability to filter on the Year field (#9 among the long listed fields). The sorted list continuously increases the 'START' year for the most recently accessed set of files. The final month printed will be the highest month that appeared in that START year. The command does its magic on the current directory, and suitably discards all entries that are themselves directories. If you expect files dating prior to 2002, change the START year accordingly.
This version also attaches to new processes forked by the parent apache process. That way you can trace all current and *future* apache processes.
