Let’s say you have a directory with hundreds of files with the wrong file names, and you’d like to replace every filename containing test with prod. (this is a contrived example). We can easily do this with the “for” command in bash, combined with a little bit of bash goodness. Today we’ll learn how to replace text in a variable in a for loop.

I have been testing Windows Home Server (WHS) for about 6 months now. I thought I would write a few things about this new product from Microsoft. Basically, WHS is meant to be a computer which will sit in your closet and deliver multimedia content to various computers and other geek gadgets around your house. You are able to create user accounts, stream music and video, and create backups to your home server. Your children can watch a movie on their computer while you listen to your favorite music or vice versa. Saving copies of your files is just like you would do at work if you put them on a network drive.

The least they could have done is have a dialog during the setup process that says “Would you like a useless icon in your system tray?”

Quite a few people have written in asking me if it’s possible to turn off Aero when on battery power to save a few precious minutes of battery life. While I dispute the claim that Aero drains the battery life, there is now a utility that will automatically turn off Aero when in battery mode so you can test it for yourself.

The new Parental Controls in Windows Vista will allow you to filter the content your children can view on the web. You could, for instance, block your kids from using MySpace or other similar sites. Before you set this up, you should make sure your child has a non-administrator account so they can’t immediately reverse the changes.

Windows is always trying to save you from yourself and with Windows Home Server it is no exception. Anytime you log on as the administrator, you receive an annoying caution message, but we can disable this annoying message from coming up every time you log on to your server.

It only took two days for somebody to come through on my offer of a bounty. Reader Shawn wrote in with a link to Vista Thumbnail Sizer, a utility written by Andreas Verhoeven, that performs exactly the features I was looking for.
