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,…):

The exported TSV file of Google Adwords' first five columns are text, they usually should collapse into one cell, a multi-line text cell, but there is no guaranteed way to represent line-break within cells for .tsv file format, thus Google split it to 5 columns.
The problem is, with 5 columns of text, there are hardly space to put additional fields while maintain printable output.
This script collapses the first five columns of each row into one single multi-line text cell, for console output or direct send to printer.

There is no longer a need to add PGP keys for Ubuntu Launchpad PPA's.
The add-apt-repository command creates a new file for the PPA in /etc/sources.list.d/ then adds the PPA's keys to the apt keyring automatically. No muss, no fuss.
