powershell-4.0

问题 Is there a simple way to prove if a network adapter is working? Perhaps some IP like localhost (127.0.0.1) which is always available regardless of which network I'm connected to; only one that only shows if my wireless network adapter's working? Or perhaps there's some simple diagnostic check to confirm this? I've tagged this question as PowerShell as that's my preferred language; but I can figure out ways to integrate with any other solutions which may be suggested. Tried so far I thought of

问题 I'm currently automating the creation of scheduled tasks via Powershell, and I'm using the New-ScheduledTaskAction , New-ScheduledTaskTrigger , and Register-ScheduledTask commands. Now, I have a few jobs that need to run under the following conditions : Run once every Friday Run once on the 1st of every month Run once on the 10th day of every month While the technet documentation for the New-ScheduledTaskTrigger command specifies a Daily and Weekly time span parameter, I do not see one for

问题 I encountered a bug in a script I wrote this morning where I wasn't getting an output from my Select-String expression. After a bit of playing I realized that this expression would not return the value of my match in v2.0 but would in v4.0 where I originally wrote it. ($log | Select-String "\[CIsoCreator\] Creating iso file" -AllMatches | Select-Object -ExpandProperty line -Last 1 | Select-String "([A-Z]\:)(.*\\)*.*\.iso").matches.value After trying a few things I ended up with this which

问题 Is there a better way to be able to count the amounts of empty groups than using this method and then calling $count + 1 for each result? I tried to mess around with $123.count but it kept returning 0 $Groups = Get-ADGroup -Properties * -Filter * | where { $_.Members.Count -eq 0} $123= Foreach($G In $Groups) { $Membership = Get-ADGroupMember -Identity $G.Name If($Membership.count -eq 0){ $Count = $count + 1 } } 回答1: Get-ADGroup can do much of what you ask without going away from AD. Getting

问题 Background The following code returns the IPv4 address of a given alias or host: [System.Net.Dns]::GetHostAddresses('someDnsName').IPAddressToString The below code returns the HostName (CName) and aliases of an IP: [System.Net.Dns]::GetHostByAddress('172.12.34.56') I'd therefore expect anything which returns an IP on GetHostAddresses to be listed under the HostName or Aliases of a call to GetHostByAddress (or at least for the FQDN of that item to be listed). i.e. I'd expect the result of the

I "think" I understand the concept of placing the expression first (ahead
