Report all files less or = to 1KB - powershell

Question

I am trying to create an alert that will look at directories and email a listing of all files that are 1kb or less. Currently it is sending one email for every file. I want the offending files to be in one email.
$date= Get-Date -Format yyyyMMdd
$path= "c:\test\$date"
$files = Get-ChildItem -Path $path -Recurse
$body = "These files are too small."
$body += "<table><tr><td><b>Filename</b></td></tr>";
foreach ($file in $files) {
if ($file.Length -lt 1kb) {
$body += "<tr><td>" + $($file.Name) + "</td></tr>"
}
};
$body += "</table>"
foreach ($item in [System.IO.Directory]::GetFiles($path)) {
$a=get-item($item)
if ($a.Length -lt 1kb) {
Send-MailMessage -From noreply#email.com -To person#email.com -Subject "Files small" -Body $body -BodyAsHtml -SmtpServer 0.0.0.0
}
}

Answer 1

You're looping twice. Simply remove the loop around Send-MailMessage:
$body += "<table><tr><td><b>Filename</b></td></tr>"
foreach ($file in $files) {
if ($file.Length -lt 1kb) {
$body += "<tr><td>" + $($file.Name) + "</td></tr>"
}
}
$body += "</table>"
Send-MailMessage -From noreply#email.com -To person#email.com -Subject "Files small" -Body $body -BodyAsHtml -SmtpServer 0.0.0.0
You can add a flag variable to indicate whether files were found or not:
$body += "<table><tr><td><b>Filename</b></td></tr>"
foreach ($file in $files) {
if ($file.Length -lt 1kb) {
$fileFound = $true
$body += "<tr><td>" + $($file.Name) + "</td></tr>"
}
}
$body += "</table>"
if ($fileFound) {
Send-MailMessage -From noreply#email.com -To person#email.com -Subject "Files small" -Body $body -BodyAsHtml -SmtpServer 0.0.0.0
}
