File Extension Change Shortcut
Changing the extension of a file seems like something you would do often enough to know how to do it from command line. One annoying part of moving a file is repeating the file name a second time when all I want to do is change the extension. A minor annoyance but an annoyance nonetheless.
I recently found that you can quickly change a file's extension with this handy shortcut:
# mv filename.{old,new}
mv code.{txt,js}
The braced syntax provides a way to quickly swap out the file extension without needing to repeat the file name. Sweet!

![MooTools-Like Element Creation in jQuery]()
