A client for the microblogging service Twitter. The difference with other clients is that this is a 100% text-based command line, yet fully functional application.
In interactive mode, it is a fully interactive client with asynchronous background updates and commands. It supports ANSI colour, hashtags and Twitter Search.
From the command line, use it to update your Twitter in shell scripts, from cron, and so on. TTYtter is extensible and you can run it in daemon mode to make your own Twitter bot.
