Runs Previous Command with Replace
For some reason most of my typos happen within iTerm, which is kind of funny when you consider most commands are super short. gut push doesn't do what I want, nor does hg ammend or any other command spelled wrong. Then you have to either retype the whole thing or press the up key, place the cursor in the right spot, then update the bad text. Blah.
I recently learned a cool trick for executing the previous command but with a text replacement shortcut:
# `gut push` -- Oooops!
^gut^git # Replaces "gut" with "git" and executes previous command!
# `hg ammend` -- Oooops!
^ammend^amend
No need to retype and no need to fix the text within the entire command. Neat way to save time and get things done!

I love almost every part of being a tech blogger: learning, preaching, bantering, researching. The one part about blogging that I absolutely loathe: dealing with SPAM comments. For the past two years, my blog has registered 8,000+ SPAM comments per day. PER DAY. Bloating my database...

While synchronous code is easier to follow and debug, async is generally better for performance and flexibility. Why "hold up the show" when you can trigger numerous requests at once and then handle them when each is ready? Promises are becoming a big part of the JavaScript world...

My new MooTools plugin, ElementFilter, provides a great way for you to allow users to search through the text of any mix of elements. Simply provide a text input box and ElementFilter does the rest of the work.

When I first saw MooTools graphical navigation, I was impressed. I thought it was a very simple yet creative way of using Flash. When I right-clicked and saw that it was JavaScript, I was floored. How could they achieve such...
Really cool trick, David! Hadn’t come across this one yet. I’m the curious type so I just had to know what this is called, and any other details… It looks like after a little research that this is a Bash feature, and it’s called “quick substitution”. Its documented under the “Event Designators” section of Bash documentation:
http://www.gnu.org/software/bash/manual/bashref.html#Event-Designators
The documentation specifies the usage as:
But I just tried it out myself and it looks like it works just fine without the trailing caret character. By the way, it’s probably worth noting that this will only replace the first instance of “string1” in the command, so if you misspelled something twice in the command (seems unlikely, I know) you would have to use:
This works with Zsh too.
Thanks Rose Hosting, good catch!

If you use zsh, you can enable auto-correction, so if you type

This is a great tip.
