Is it safe to use ALIASES in scripts?

In our newsgroup (Microsoft.Public.Windows.Server.Scripting) , Mark Ayers asked the question:> Shouldn't best practice for scripts be full command name? The answer is YES, NO, and MAYBE.

Finding out what determines which properties are displayed

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 ...

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

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.

Using-Culture -Culture culture -Script {scriptblock}

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...
