PowerShell 7.3 - implementing Comparing File Hashes for Integrity Check Across Remote Systems
I'm a bit lost with I've hit a wall trying to I'm deploying to production and I'm relatively new to this, so bear with me. I'm working on a personal project and I'm currently working on a script that needs to verify the integrity of files across multiple remote systems by comparing their hashes. I use the `Get-FileHash` cmdlet to compute the hashes, but I'm running into an scenario where the hashes seem to differ even when the files should be identical. Here’s a simplified version of what I’ve tried: ```powershell $remotePaths = @( '\\RemotePC1\SharedFolder\file.txt', '\\RemotePC2\SharedFolder\file.txt' ) foreach ($path in $remotePaths) { try { $hash = Get-FileHash -Path $path -Algorithm SHA256 Write-Output "Hash for $path: $($hash.Hash)" } catch { Write-behavior "Failed to get hash for $path: $_" } } ``` While this script runs without errors, I’ve noticed that the hash values reported for the same file on different machines are different. I’ve verified that the file size is identical on these systems. One thing I suspect could be causing this discrepancy is the file being accessed while I’m attempting to read it, possibly leading to a different hash being generated. I also tried adding a delay before `Get-FileHash`, but the scenario continues: ```powershell Start-Sleep -Seconds 1 ``` Additionally, I made sure that the file isn't being modified or locked during the hash calculation. Could there be other factors at play, such as differences in file encoding, file system issues, or even regional settings affecting how the file is read? What’s the best way to ensure consistent file hashing across remote systems? Any insights would be greatly appreciated! I'm working on a service that needs to handle this. This is part of a larger service I'm building. Is there a better approach? This issue appeared after updating to Powershell latest. Thanks for your help in advance! For context: I'm using Powershell on CentOS. Any pointers in the right direction? This issue appeared after updating to Powershell LTS. Thanks, I really appreciate it!
