Hi, To Oscar Virot,

Why use [int]('a')[0] rather not [int][char]'a' ?

To Oscar Virot,

Why not use [int]('a')[0] rather not [int][char]'a' ?

I thought [int][char]'a'..[int][char]'z'|%{[char]$_} is the same as your examples

Hey.

But even without remembering the ASCII table you can still enumerate a-z.

Remember that you also can cast a Character back to an integer. But just trying [int]'A' wont work. Powershell thinks its a string so we need to make it a single character first. [int]('a')[0] returns 97.

So the command for enumerating a-z without knowin ASCII is:

[int]('a')[0]..[int]('z')[0] | % { [char]$_ }

Your trick #10, Converting WMI date to DateTime objects is SO cool! I have written a vb function to do exactly this. Thanks.

BTW, in Trick #8, why not just use the following (I think easier and more readable) code to get the same result?:

Get-Command -CommandType cmdlet | ForEach-Object { Get-Help $_ -Examples}
