Create a Custom Detection Script for Sublime Merge (PowerShell)

Microsoft Endpoint Manager Configuration Manager (MEMCM / SCCM) and Microsoft Intune use Detection Rules to determine the presence of Applications & Win32 Apps. The detection rules ensure that application installations only begin to run if the application is not already installed on the device. This article will serve as an informative guide and give you a clear understanding of how to create an updated custom detection script for each new version of Sublime Merge using PowerShell.

How to Create a Custom Detection Script for Sublime Merge

Sublime Merge (File Detection Method)

• Install the version of Sublime Merge you want to deploy on a test box or VM
  • Check out the following posts for further details
    • Sublime Merge Silent Install (How-To Guide)
    • Sublime Merge Install and Uninstall (PowerShell)
• Open Windows PowerShell ISE by Right-Clicking on Windows PowerShell ISE and selecting Run as Administrator
• Copy the following code into the Windows PowerShell ISE

## Check for Sublime Merge (File Detection Method)
$SublimeMergeExe = (Get-ChildItem -Path "C:\Program Files\Sublime Merge\sublime_merge.exe" -ErrorAction SilentlyContinue)
$SublimeMergeExe.FullName
$SublimeMergePath = $($SublimeMergeExe.FullName).Replace("C:\Program Files\","")
$FileVersion = (Get-Item -Path "$($SublimeMergeExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw

## Create Merge File with Sublime Merge File Detection Method
$FilePath = "C:\Windows\Temp\Sublime_Merge_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$SublimeMergePath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw -ge `"$FileVersion`"){"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "Exit 0"
Add-Content -Path "$FilePath" -Value "}"
Add-Content -Path "$FilePath" -Value "else {"
Add-Content -Path "$FilePath" -Value "Exit 1"
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath

• Click Run Script (F5)
• A text file will open with the Sublime Merge Detection Method script required to detect the current version of Sublime Merge that is installed on the device you are running the script from.

Example:

If([String](Get-Item -Path "$Env:ProgramFiles\Sublime Merge\sublime_merge.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw -ge "2.0.7.9"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
