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,…):

Sometimes I need a quick visual way to determine if there is a particular server who is opening too many connections to the database machine.
The sample output, is a display of the values you can change, using this command. After a change of of these settings you will need to reload the box, by typing...wait...wait for IT: 'reload'. This comes in handy when working with the RX hardware, for example, which has a base limitation of 32 (RSTP (802-1w) instances. For all of you paying attention that means if you run RSTP on a RX you can only have 32 VLANs. Sure, you can have common groups of VLANs, like back in the day style MSTP, PVST, PVST+ (and all that old STP (802.1d) mess), before "per vlan spanning-tree", RSTP (802-1w), was made. But who wants to do all that?
Remove all arquives except the list.
Can't have space between the commas.
Forward connections to $HOSTNAME:8080 out to $HOST:80
Original submitted version would break if any filenames had whitespaces in them. The command is a Bad Idea anyhow, because you will end up `cat`ing a binary or something else specacularly bad.
PmWiki stores wiki pages as Group.Name. Simply split the directory listing and count frequency of group occurances.
Show the maximum settings in effect for PHP at the command line.
Recursively remove .svn directories from the current location.
Dump 389ds schema, putting "\n " on one line with perl.
You have to specify the objectclasses, attributetypes operational attributes too, otherwise they won't be dumped!
For quick validation of folder's file-contents (structure not taken into account) - I use it mostly to check if two folders' contents are the same.
An alias i made for myself to play music in a faster way.
Works great when you have Guake / Tilda installed (Console that drops down like in the game QUAKE)
I put this in my bash_alias file (I'm on ubuntu, the bash_alias file does autostart with the right config) but it works putting it in bashrc too. Or anything that autostarts when the console is opened.
Needs Mplayer and music files to work. With out music theres nothing to play!
Oh, and also, without modification, this alias will try to play stuff from your ~/Music folder! (case sensitive). Make sure that folder exists and has music OR edit this alias to fit your needs.
See external ip with w3m, simple and fast.
On a web site from Chile (spanish).
You don't want the -ar parameters in this case. The man page for BASH_BUILTINS(1) states:
"-a option means to remove or mark all jobs" and
"-r option without a jobspec argument restricts operation to running jobs"
In this case we are supplying the process id of the job to disown so neither of these should be used.
The first grep rejects capitalised words since the dict has proper nouns in it that you mightn't want to use. The second grep rejects words with ending in apostrophe s, and the third forces the words to be at least 15 characters long.
