PowerShellPlus v2.1 Beta

This is sort of exciting - PowerShellPlus v2.1 Beta is live! I’ve used PowerShell Plus for some time and love it. But there are things that I’d like to see, in particular the CTP3 support. Well, now we have that – and I’m downloading it as I write this post. The features in 2.1 that catch my eye are: VBS support, STA MOde, Code Sharing and of course, CTP3 support. I’ll be posting more once I have the code running and have a chance to give it a good test!

Updates on A Grateful Dead PowerShell Script

I really love mixing two of my favourite things: the good old Grateful Deal and PowerShell. I’ve posted a couple of scripts that examine my live show archive. Yesterday, I was able to spend some time updating my Count-GDSHows script. In Count-GDShows2.ps1, I added a couple of features. First I worked out how many shows are recording using the SHN format and how many in FLAC (plus how many are not noted in the folder name). Second, I timed the script, although the timing varies widely thanks to disk caching!

My GD (and my Jerry Garcia) archive is stored on a couple of external USB disks. I have separated Jerry shows from GD shows and have both stored on disks plugged into separate machines. I use the folder name of each show to define the date, type (aud vs sbd) and encoding format. So a show in “gd69-04-22.sbd.clugston.68.sbeok.shnf” is a soundboard encoded in the Shorten format, for a show on April 22 1969. Were you even alive then?

I wonder how many of this blog’s readers collect Grateful Dead shows? I have a standing offer that I’ll repeat: If you want the shows in my collection, send me a big disk and I’ll xcopy!

1. <# 
2. .SYNOPSIS 
3.     Counts the Grateful Dead shows in my archives and displays 
4.     details of the collection. 
5. .DESCRIPTION 
6.     This script looks at my GD archive, and uses folder names to 
7.     determine show type (aud, sbd, etc), and checks to see what 
8.     shows have checked MD5s. The script also times itself. 
9.      
10.     This is an update to an earlier script that adds separate  
11.     counts for FLAC and SHN shows.
