One of the great strengths of PowerShell is that the commands can read like a sentence. A person with a basic understanding of PowerShell should be able to look at a script and have an understanding of what is happening.
Additionally, Shared scripts (whether shared internally in your organization or externally in to the world) will be read far many more times then they are written. In order to increase the readability of a script, using variable and function names that are very descriptive make it that much easier to maintain and update for anyone.

Good tip! Especially if you have a pretty complicated scriptblock.

This is great tip and shows how adding a few extra lines of code can really make things cleaner and easier to read.

One can also use variables in the Expression script blocks, but they must be defined beforehand and sometimes as :
$expression_variable = but I am not sure when to execute the script block. The usage is then Expression = $expression_variable

Thanks Wes. Hash tables are a great lightweight for mappings and lookups. I’ve just used them that way for a data conversion project I’m working on.

Nice use of HashTables. I find myself using them everywhere, especially for simple mapping/lookups. Good stuff!

Like I said Jeff, I enjoy your columns. Even though I’ve been using PowerShell for quite some time now, your column provides a great reminder as to some less obvious or common features and capabilities.

Great suggestions. I was trying to stick to a one-liner but scriptblocks make total sense and perfectly appropriate for a scripted solution. Thanks for your interest and support.

Very nice… I love it! This just show that you can go many different directions when you’re building your script.
