email to check size / if it's complete - powershell

Question

Running the following script:
$FileToCheck = Get-Item -Path $folder/test.zip -ErrorAction SilentlyContinue
$EmailSplat = #{
To = 'business#email.com'
CC = 'admin#email.com'
#SmtpServer = 'smtp.server.net'
From = 'my#email.com'
Priority = 'High'
}
$folder = "C:\test\"
# first condition: 'If the file does not exist, or was not created today, an e-mail should be sent that states "File not created" or similar.'
if ((-not $FileToCheck) -or ($FileToCheck.CreationTime -le (Get-Date).AddDays(-1))) {
$EmailSplat.Subject = 'File not Found or not created today'
$EmailSplat.building = 'This is the email building'
Send-MailMessage #EmailSplat
# second condition 'If the file exists and was created today, but has no content, no e-mail should be sent.'
} elseif (($FileToCheck) -and ($FileToCheck.Length -le 2)) {
#third condition and the default condition if it does not match the other conditions
} else {
$EmailSplat.Subject = 'Active Directory Accounts To Check'
$EmailSplat.building = Get-Content -Path/test.zip //maybe add the file??
Send-MailMessage #EmailSplat
}
Goal: Check if file .zip is complete, once is complete it sends an email to let business that file is good to go. I'm running the script, getting no errors but no alert emails either.
Build on: Add maybe a time that the email could be sent. For example, script will run every morning, at 6:00 the email gets sent to users to notify that the file is complete.

Answer 1

The $Folder variable needs to be on the line before the "$FileToCheck = Get-Item..." line since it uses that variable.
There is no such parameter "building" in the Send-MailMessage cmdlet. I think you are after Body, since you are trying to Get-Content...?

Another note is that Get-Content won't be able to read the contents of a zip file. You would need to unzip the file then read the file or add the file as an attachment.
This is an example of using Get-Content on an zip file that has only a text file in it:
PK
ï¸ÌN_S³ test.txtsdafasdfPK
ï¸ÌN_S³ test.txtPK 6 .

Answer 2

Add $ErrorActionPreference = "Stop" at the top of the script, so errors are shown.
Use the Attachments parameter to add files, building is not a valid parameter of Send-MailMessage
Get-Content is not needed, just add the path to the attachment:
$EmailSplat.Attachments = "Path/test.zip"
So something like this:
$ErrorActionPreference = "Stop"
Set-StrictMode -Version Latest
$folder = "C:\test"
$fileToCheck = Get-Item -Path (Join-Path $folder test.zip) -ErrorAction SilentlyContinue
$emailOptions = #{
"To" = "business#email.com"
"CC" = "admin#email.com"
"SmtpServer" = "smtp.server.net"
"From" = "my#email.com"
"Priority" = "High"
}
# first condition: If the file does not exist, or was not created today, an e-mail should be sent that states "File not created" or similar.
if ((-not $fileToCheck) -or ($fileToCheck.CreationTime -le (Get-Date).AddDays(-1)))
{
$emailOptions.Subject = "File not Found or not created today"
Send-MailMessage #emailOptions
}
elseif ($fileToCheck -and ($fileToCheck.Length -le 2))
{
# second condition: If the file exists and was created today, but has no content, no e-mail should be sent.
}
else
{
# third condition and the default condition if it does not match the other conditions
$emailOptions.Subject = "Active Directory Accounts To Check"
$emailOptions.Attachments = $fileToCheck.FullName
Send-MailMessage #emailOptions
}
