April 25th, 2006
MoW, a Monad newsgroup regular, asked why only the Caption, Name and PeakUsage properties were displayed from the command “get-WMIObject Win32_PageFileUsage” while the output object had a lot more properties. I think it is worth it to explain in details how to find out which properties are displayed.First, I would look at which view ...

Kurt asked the question "why not Noun-Verb vs Verb-Noun" in his post: http://blogs.msdn.com/monad/archive/2006/02/16/533522.aspx#574708 There are lots of answers to this some better than others.  Let me rattle off a couple of them: VMS DCL/AS400.  Issac Newton once said that if he could see farther, it was because he was ...

Comparative Examples in MSH and KSH

April 25th, 2006
  Most shells (such as Windows CMD.EXE and the UNIX shells SH, KSH, CSH, and BASH) operate by executing a command or utility in a new process, and presenting the results (or errors) to the user as text. Text-based processing is the way in which system interaction is done with these shells. Over the years, a large number of text ...

Sunday morning drive with my hair on fire: Types/Community/Synthetic types/Democracy/Cool XML tricks

April 25th, 2006
Exploring types is a pain! Monad provides Get-Member which makes it pretty nice to explore an OBJECT but if you want to explore that object's type, you have to use the capabilities of the System.RuntimeType class. Let me make that distinction a little clearer.  Imagine that I've got some xml:$x=[XML]"<a><b>TEST</b><a&...

A bit about Scriptblocks

April 25th, 2006
When scripting with MSH one of the most useful things to know about are scriptblocks (lambda functions).  Scriptblocks are compiled bits of MSH script which you can pass around and invoke whenever you feel like it.  They turn out to be so useful that if you look at the cmdlets you’ll find a few that take scriptblocks (foreach-...

PINVOKE or accessing WIN32 APIs

April 25th, 2006
In the very early days of Monad, we focused on a world where everyone would publish Cmdlets and providers.  Cmdlets and providers were designed around providing the best user experience.  They provide the right, high-level, task-oriented abstractions that users want while also providing the semantic benefits that ...

Using-Culture -Culture culture -Script {scriptblock}

April 25th, 2006
One of the traditional challenges with scripting is dealing with different CULTURES.  Imagine the case where you are writing a script and you'll have to parse datetime string from different cultures.  If it was just one culture, you could set the process culture and be done with it.  Here is a function that allows you to...

April 25th, 2006
Did your command or script fail and/or report an error?  We hope to have a proper script debugger in a future version, but until then, MSH has some handy features to help you figure out what went wrong.  In this series of blog entries, I will present some of those features.  Thanks to Jim Truher [MSFT], Bruce Payette [MSFT], ...
