    Tweet from Command Line with t

    I've been obsessed with command line magic lately, as you may have noticed.  I don't plan on using every utility I've written about but I'm having fun learning about what's out there and how it's done.  My latest quandary was how one could tweet and perform other Twitter-centric tasks...

    With all of my recent command line tutorials, I've really gotten excited about the shell's simplicity and realized the true power of using the underlying technology of pretty UIs.  Since I work from home, I spend a lot of time on video calls, so when...
