I was going to post a blog entries and realized that the example I wanted to give used some of my utility functions so I’ll share them first. I hope you find them interesting. I put them in a file called LibraryTime.ps1 and dot source that during my login. BTW – everyone should adopt that pattern. Files that contain functions meant to be dot sourced into another script should be called LibraryXXXX.ps1<\/p>\n
