Using Set-Content To Modify Your Scripts

1 minute read

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:

    1

    12
    13
    14

    16
    17
    18
    19
    20
    21
    22
    23
    24
    25
    26
    27
    28

    30
    31
    32
    33
    34
    35
    36
    
    # 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
