In my previous post about Boolean Values And Operators I made the following point: "PowerShell has a rich notion of TRUE/FALSE because it dramatically reduces the overhead and junk that you need to deal with when doing your work."  This philosophy flows from Whitehead's observation:   Civilization advances by extending the number ...

John Smith asked what TRUE and FALSE were in PowerShell on our newsgroup Microsoft.Public.Windows.PowerShell.   The simple answer to this is $TRUE and $FALSE but the complete answer is a richer.  PowerShell has a very rich notion of TRUE and FALSE.  The best way to explain it is to show it.  PS>  function test...

I love the fact that we designed PowerShell for Admins and IT Pros and love to demonstrate what that means.  Often I'll demo PowerShell and show how you can use "KB", "MB", and "GB" as I did in my previous blog entry: PS> 1kb1024PS> 1mb1048576PS> 1gb1073741824PS> 1kb+2mb+3gb3223323648 Almost uniformly, the crowds LOVE this but...

Jeffery Hicks as a very nice File Aging script.  The thing that Iike about it is that it provides a very good illustration of how to use a number of PowerShell features including: He had one technique that could be improved.  Here is a line from the script:  $GrandTotal="{0:N2}" -f ($GrandTotal/1048576) The question is, what i...

You might have noticed that “findstr” does not work properly with non-English text in PowerShell. For example: Let’s create a text file with some Chinese characters in it. PS C:\> ${c:\test.txt}="中文" Try to use findstr to find  one of the Chinese characters, and it did not find anything. PS C:\> Get-Content test.txt | findstr /c:中 The sa...
