I did a test tonight and the sound is definitely better over Lync.  The sound wasn’t perfect but was much better than Live Meeting. Actually, seemed usable. The system seems a lot more responsive in terms of client screen refresh. When showing slides the client refreshes very quickly.  Showing code seemed better – not as […]

UK PowerShell group

Posted by: | June 25, 2013 | 3 Comments |

As you are probably aware the UK PowerShell group has been very quiet over the last few months. This has been due to my personal circumstances – hopefully now resolved. I want to re-start the group and was wondering what people wanted. When I started the group 6 years ago we were the only PowerShell […]

In my last post I showed how to relate find the groups of which a local user is a member. A comment was left asking about the inverse relationship. In this case we can just turn the code round. Get-CimInstance -ClassName Win32_Group | foreach { $users = Get-CimAssociatedInstance -InputObject $psitem ` -ResultClassName Win32_UserAccount | select […]

A question came up on the Powershell.org forum about finding the groups of which  local accounts are members You can get account data using Win32_UserAccount Group information is held in Win32_Group. You can see the relationship between users and groups by dumping the Win32_GroupUser instances. You will see a load of entries like this GroupComponent […]

Touching files

Posted by: | June 24, 2013 | No Comment |

Unix has a command called touch that allows you to set the access time on a file.  PowerShell doesn’t have a direct equivalent but it is very easy to perform the same task: $date = (Get-Date).AddMonths(-2) Get-ChildItem -Path C:\Teszzt2 -Filter f*.txt | Set-ItemProperty -Name LastWriteTime -Value $date -PassThru | Set-ItemProperty -Name LastAccessTime -Value $date -PassThru […]

Clearing Event logs

Posted by: | June 23, 2013 | No Comment |

I needed to clear some event logs on a test machine. Rather than picking and choosing I’ll clear them all Get-EventLog -List | where {($_.Entries).Count -gt 0} | foreach {Clear-EventLog -LogName $_.Log}   The interesting part is the where-object filter in that Entries is a collection of the Entries in the log. If you want […]

I was on a course last week and one attendee uttered words to this affect “I won’t automate – it takes to long to write the code. I’ll keep doing it manually” You may be able to do it faster the first time by performing the task manually. I can guarantee that the second time […]

I noticed code like this in quite a few entries in for Event 1 Get-ChildItem -path C:\Application\log -Recurse -Filter *.log | Where-Object{$_.LastWriteTime -lt [DateTime]::Now.Subtract([TimeSpan]::FromDays(90))} | ForEach-Object {…} From the title it should be obvious that there’s something I don’t like.  The where-object re-calculates the date to test for EVERY object on the pipeline. That’s not […]
