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.
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,…):

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:
Adds up the total memory used by all Stainless processes: 1 Stainless, 1 StainlessManager and 1 StainlessClient per tab open.
Sometimes, you don't really care about all the other information that ifconfig spits at you (however useful it may otherwise be). You just want an IP. This strips out all the crap and gives you exactly what you want.
besure to adjust your find to use to correct location of your VMX files.
I took java to make the find command simpler and to state that it works for any language supported by cpp.
cpp is the C/C++ preprocessor (interprets macros, removes comments, inserts includes, resolves trigraphs). The -fpreprocessor option tells cpp to assume the input has already been preprocessed so it will only replace comment lines with blank lines.
The -L 1 option tells xargs to launch one process for each line, indeed cpp can only process one file at the time...
See external ip with w3m, simple and fast.
On a web site from Chile (spanish).
You can use -e to pass multiple patterns.
Use multiple patterns with grep -v. So you can print all lines in a file except those containing the multiple patterns you specify.
Sample command to obtain a list of geographic localization for established connections, extracted from netstat. Need geoiplookup command ( part of geoip package under CentOS)
uses the previous "chr" function and uses it to create the inverse function "ord" by brute force.
It's slow, It's inelegant, but it works.
I thought I needed ord/chr to do a cartesian cipher in shell script a whie ago, but eventualy I realized I could get fancy with tr and do the same thing...
not my cmd... found on the web
Place this in your .bash_profile and you can use it two different ways. If you issue 'h' on its own, then it acts like the history command. If you issue:
Then it will display all the history with the word 'cd'
miss a class at UTOSC2010? need a refresher? use this to curl down all the presentations from the UTOSC website. (http://2010.utosc.com) NOTE/WARNING this will dump them in the current directory and there are around 37 and some are big - tested on OSX10.6.1
If you want prepend/append text just wrap in echo:
echo Connected: `netstat -an|grep -ci "tcp.*established"`
No need for -l and the output can be sent directly into another function expecting directory names.
Searches for all .project files in current folder and below and uses "svn info" to get the last changed revision. The last sed joins every two lines.
Filters out all non-insert SQL operations (we couldn't filter out only lines starting with "INSERT" because inserts can span multiple lines), quotes table names with backticks, saves dump to a file and pipes it straight to mysql.
This transfers only data--it expects your schema is already in place. In Ruby on Rails, you can easily recreate the schema in MySQL with "rake db:schema:load RAILS_ENV=production".
