Description:

So like many other scripters, I find that I often want my PS files to follow a certain template, so I created a function that will both insert and append predefined text to my scripts so that I can just open VS Code and modify the “body”. Here goes:

To Resolve:

1. Use the following:

   # Edit these extensions to the type of files you want to add content to.
   $Include = @("*.txt", "*.ps1", "*.log")
   
   # $Source = Get-Childitem "C:\Test" -Include "$Include" -Recurse
   $Source = Get-Childitem "C:\Test" -Include "$Include"
   
   Foreach ($File In $Source)
   {
   
   Write-Output "Processing $File ..." 
   
   # Remember to use the escape character "`" before every dollar sign and ` character. For example `$myVar and ``r``n (new line)
   $Preformatting = @"
   Multi-Line
   Text
   To
   Insert
   At
   Top
   "@
   
   $CurrentFile = Get-Content $File
   
   $PostFormatting = @"
   Multi-Line
   Text
   To
   Insert
   At
   Bottom
   "@
   
   $Val = -Join $Preformatting, $CurrentFile, $PostFormatting
   Set-Content -Path $File -Value $Val
   Write-Output "$File rewritten successfully"
   }

2. At first I couldn't get this to work unless I moved the files to a new directory, but after a couple hours of research, I can say this does work. It will keep the original files in their current folders.

3. Source is maintained under gwFileSystem
