Follow the Tweets.

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.

Psst. Open beta.

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:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Terminal - fetch all revisions of a specific file in an SVN repository

exported files will get a .r23 extension (where 23 is the revision number)


There is 1 alternative - vote for the best!

Manages everything through one sed script instead of pipes of greps and awks. Quoting of shell variables is generally easier within a sed script.

finding a specific revision where you had a specific piece of code.

I'd love to hear about any better way to search my repo without any 3rd party tools

I don't use SVN so I don't know the specific command. If you're looking to find which revision added a line that is in the current revision you probably want to use svn annotate. That should give you the revision the line was added and you can call that one right up.

If you're looking for lines of code that don't exist in the current revision, I can't help you with that. There very well might be a command, but that isn't something I've ever had the need to do with any RCS I've ever used.

wonko is right to mention svn annotate, or as I prefer it, svn blame. If you're using KDE, kdesvn, a Konqueror-integrated SVN client is a handy tool that I use from time to time when I really need to dig into subversion history and the command line gets a little tiring. Great command!
