Remove Blank Lines From a File with PowerShell

When importing a file full of data into a test system, I discovered that the CSV library I was using to do all the work was stopping when it reached a blank line. That makes sense, it thinks the data has ended. On inspection, I found quite a lot of blank lines, so there was […]

Use PowerShell to Send All Regex Matches to a New File

Yesterday I had to look at a list of stuff on a third-party website and match it up to a list of stuff we control. It took quite a bit of time and some Excel shenanigans to complete the task and as I know it’s going to crop up again, I decided to employ PowerShell […]

Update Work Items with Build Number During vNext Builds
