问题 I'm trying to get a directory off of the user's home directory in a script. This is what I'm trying, but the ~ is interperated as a literal instead of expanding to the home directory. Is there anyway to get it to expand? If not, can I get the home directory another way? $mySourceDir = "~/Projects/svn/myProject/trunk" # Single quote also does not expand cd $mySourceDir This is using the PS 6 beta on OSX. 回答1: In PowerShell, the most robust way to refer to the current user's home directory is

问题 I have a set of test DLL's that I'm running from a powershell script that calls OpenCover.Console.exe via the Start-Process command. I have the -returntargetcode flag set After execution I check $lastexitcode and $? . They return 1 and True respectively all the time. Even when tests are failing.

问题 The current selection of 16 colors from Console Colors is not the right choice for me. I would like to use much darker variants of these for the background. I could definitely set these using the UI and changing the RGB value there. For example, I could choose Darkblue and select 65 for Blue in the RGB section(128 is the default). Could some one tell me how to do this programmatically. Something like: (Get-Host).UI.RawUI.BackgroundColor=DarkBlue But with additional options. 回答1: This old post
