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.

The braced syntax provides a way to quickly swap out the file extension without needing to repeat the file name. Sweet!
