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,…):

I alias this as "tach":
alias tach='screen -x `screen -ls | grep Detached | cut -c -10`'
If you have several detached sessions it will just grab the first one. If you're running nested screens you can open new outer windows and run tach repeatedly to grab all the detached sessions into that one.
Gets the internal and external IP addresses of all your interfaces, or the ones given as arguments
Kudzu is available on CentOS, used for configuring and detecting new hardware device installed, is also usefull for device listing.
--basic --user username:password
This will authenticate your Twitter username and password
Send data to the API with POST HTTP form.
Useful after a complete system update (without a new kernel) when you want to know, which processes need to be restarted
For disk space constraint testing. Leaves a little space available for creating temp files, etc. Easily free up the used disk space again by deleting the dummy00 file. Can tailor the testing by building smaller 'blocks' to suit the needs of the testing.
WARNING: do not do this to the '/' (root) filesystem unless you know what you are doing... on some systems it could crash the OS.
A few characters shorter that the other command
I don't know why this ain't written as simply as it is. I always see it's just used as parameter, like: vi `!!`
But i use it to repeat a command, as i always work on several shells and check the result of one shell on a second.
these are some aliases you can use in bashrc to shorten the amount of typing needed to use apt-get, also can be used as reference if you can't remember alot of commands or command parameter variations,etc...
Please comment with more apt-get aliases if I missed any, thx
Shows you the geolocation of an IP address.
* Squid in reverse proxy mode
* Django's cache framework
* or CDN, like Akamai
Telnet will make a tcp connection to a remote ip/port to test connectivity. If it times out, it's not reaching the host (maybe the firewall is blocking it). If connection is refused, it's reaching the host, but either the service is not listening on that port, or it's locked.
curl doesn't provide url-encoding for 'GET' data, it have an option '--data-urlencode', but its only for 'POST' data. Thats why I need to write down this commandline. With 'perl', 'php' and 'python', this is one liner, but just I wrote it for fun. Works in Ubuntu, will work in all linux varients(I hope it will work in unix varients also).
Use this command to see logs update in real time
This will temporarily add the current directory to your $PATH. Allowing you to execute from that directory for the duration of the session.
works like a charm for the K610i
This is how I've done it in the past
Isn't that simplier huh?
due to bug can not comment
This command will open up the two files in FileMerge on OS X. You can also compare two directories.
opendiff directory1 directory2
NOTE: FileMerge is a part of the OS X Developer Tools, available on the install disc.
An example config file is placed in the sample output along with the command line call to use it.
The rsync daemon here is setup on the destination, thus requiring the read only = false flag. Also it uses uid and gid of root, change as required.
