PowerShell Tip


Insert String Every N Characters


http://blog.expressionsoftware.com/2010/03/insert-string-every-n-characters.html

This PowerShell v2 script inserts a string every N characters. The interval is specified using the regex repetition operator, {min,max}.
$a = 'abcdefghijklmnopqrstuvwxyz'
([regex]::matches($a, '.{1,3}') | %{$_.value}) -join ' '
([regex]::matches($a, '.{1,8}') | %{$_.value}) -join '..'
([regex]::matches($a, '.{1}') | %{$_.value}) -join '-'

#output
abc def ghi jkl mno pqr stu vwx yz
abcdefgh..ijklmnop..qrstuvwx..yz
a-b-c-d-e-f-g-h-i-j-k-l-m-n-o-p-q-r-s-t-u-v-w-x-y-z

Removal of $_ and also $PSItem in PS v3

In PowerShell, the variable "$_" has special importance. It works like a placeholder in scenarios like this one:
PS> Get-ChildItem $env:windir | Where-Object { $_.Length -gt 1MB }
In PowerShell v3, there is an alias for the cryptic "$_": $PSItem. So now code can become more descriptive:
PS> Get-ChildItem $env:windir | Where-Object { $PSItem.Length -gt 1MB }
Then again, in PowerShell v3, "$_" isn't necessary in many scenarios anymore at all. You could also write:
Get-ChildItem $env:windir | Where-Object Length -gt 1MB

PowerShell Gotcha



Numeric values as the first character in parameter names:


function foo {
[cmdletbinding()]
param (
[parameter()]
[switch]$32bit
)
if ($32bit){
"32bit"
}
}
PS c:\> foo -32bit
foo : A positional parameter cannot be found that accepts argument '-32bit'.


Workaround! - $x86

PowerShell Gotcha

Text file with $false in it, read this into a variable and you have $false

Use it in an If Statement and what do you get (True)

You need to invoke-expression because it has a $ infront of it, so call it with powershell to actually run the powershell code so you can get the results.

[Boolean]$Var = $False
$Var = [System.Convert]::ToBoolean("$True")
