powershell

问题 If I find (or create) a new PowerShell cmdlet (or function), how do I add it to my machine? Do I copy it to a particular folder? Do I put its content in a particular file? Do I need to authorize it, or sign it, or give it permission in some way? I don't want to use it in just one session; I want it to be available whenever I use PowerShell on this machine. 回答1: As Alex mentions, any function defined in your profile or in a script that gets "dotted" into your profile will always be available.

问题 I have come across variables (or parameters) being declared like this: ${var_name} = "Hello world!" As far as I can tell, this is no different to the following: $var_name = "Hello world!" I am wondering if the {} braces in the first example do or mean anything. Do they change the behaviour of the variable? 回答1: Curly braces in PowerShell variable names allow for arbitrary characters in the name of the variable. If there are no "pathological" characters in the variable name, then the braces

问题 I can query the AD and find all the IIS sites and their virtual directories, now I need to be able to update those home directories and save the changes. After I fetch the directory entry I can display the site path using $site.Path , however setting it doesn't seem to have any effect. It never changes the actual stored path. I have tried $site.Path = <new path> and $site.Put( "Path", <new path> ) but neither have these seem to be affecting the stored path. $site = $iis.psbase.children |
