Comparing files with Powershell

I know I put something about graylog but in reality I like living off the land, basically you can compare hashes of files in every directory. repeat that same loop. Here is a script that demonstrates how to get the hash of a file using PowerShell and then compare it to a previously stored hash:

# Set the path to the file whose hash you want to compute
$filePath = "C:\path\to\file.txt"

# Compute the hash of the file using the Get-FileHash cmdlet
$currentHash = Get-FileHash $filePath

# Store the current hash in a variable for comparison later
$storedHash = $currentHash

# Wait for a specified amount of time
Start-Sleep -Seconds 3600

# Compute the hash of the file again after waiting
$newHash = Get-FileHash $filePath

# Compare the current hash to the stored hash
if ($newHash -eq $storedHash) {
    Write-Output "The hashes are the same"
} else {
    Write-Output "The hashes are different"
}

This script first computes the hash of the file using the Get-FileHash cmdlet, which is built into PowerShell. It then stores the current hash in a variable called $storedHash. After waiting for a specified amount of time (in this case, 3600 seconds, or 1 hour), it computes the hash of the file again and compares it to the stored hash using an if statement. If the hashes are the same, it outputs a message saying “The hashes are the same”. If the hashes are different, it outputs a message saying “The hashes are different”.

You can customize this script to fit your specific needs by changing the file path, the amount of time to wait, and the output messages as desired.
