Powershell Script to compare files in two different locations and for any change happen it should trigger an alert to email

Question

I am having same files in two paths "/home/azureadmin/HTML" and "/var/www/html". I want to trigger an email alert when there is a file change by comparing the files in the locations mentioned. For this can anyone help with a powershell script. Please

Answer 1

Try this (I haven't tested it):

$path1 = "/home/azureadmin/HTML"  
$path2 = "/var/www/html"  
Get-ChildItem -Path $path1 -File |  
    ForEach-Object{  
        $name2 = "{0}\{1}" -f $path2, $_.Name  
        $hash1 = Get-FileHash -Path $_.FullName -Algorithm SHA256  
        $hash2 = Get-FileHash -Path $name2 -Algorithm SHA256  
        if ($hash1 -ne $hash2){  
            # send email here  
        }  
    }  

It doesn't cover the case of a file existing in one directory and not in the other. It only uses the file in one directory to compare against a file with the same name in another directory.

Hello there,

You need Task Scheduler in addition to Powershell to achieve you trigger the mail.

You can also trigger mail when an Event ID is generated.

The Send-MailMessage cmdlet sends an email message from within PowerShell.

You must specify a Simple Mail Transfer Protocol (SMTP) server or the Send-MailMessage command fails.
