A while ago I talked about piping all of my bash commands to twitter.com. I've kind of stopped doing that now, after I maxed out at over 14000 updates in about 2 weeks, but it was fun while it lasted.
But in order to do this kind of thing nicely, I ended up writing a command line program to make it easier. Some people have noticed it at times, by poking around in my kernel.org home directory, so I might as well announce the thing publicly.
So, consider this an announcement of the tool, bti. It allows you to send tweets to twitter.com or identi.ca directly from the command line from any Linux machine. It probably works on other systems as well, but you will have to tweak the Makefile yourself.
The latest version can always be found here.
The development for the tool is done in git, and the tree can be found on the ever-awesome github.com in this repository.
