This week's TechMail is Tweeting from the command line. Basically it discusses using a shell script to send out tweets to Twitter. Interestingly enough, one of the comments posted on that tip from a TechRepublic member discusses how he setup a private twitter account so he can control who watches and has setup a similar script to tweet system information like uptime and how large the mail queue is. I never thought of using twitter that way but now that he brought it up, I think it's genius. What a great way to get system information on the road or whatever so you can keep a proactive eye on your system. Certainly cheaper than sending SMS messages to a phone, and with the abundance of twitter clients out there and Internet-on-the-phone, that seems like a really cool idea.
