Import-CSV  and remove specified values

I have a powershell script to export some account info from AD. I want to read this CSV file in and remove certain accounts. I can't do it dynamically as it's something a manager needs to specify. The CSV file output is below

"Email","FirstName","LastName","Department","whenCreated"
"User1@domain.com","UserF1","UserL1l","Cashiering","9/8/2006 11:33:53 AM"
"User2@domain.com","UserF2","UserL2l","Cashiering","9/13/2006 11:50:59 AM"
"User3@domain.com","UserF3","UserL3l","Cashiering","12/6/2012 2:51:43 PM"
"User4@domain.com","UserF4","UserL4l","Cashiering","12/6/2012 2:51:43 PM"




I'd like to be able to loop through a where clause and remove lines based on "Email address" I specify in the file. I forsee the need to add additonal accounts in the future so if I could use an array of some sort that would be best. I see a couple solutions online but not quite what I need. logic would be

Import CSV

If account is in the list below, remove the line from the CSV
"User1@domain.com"
"User4@domain.com"
"User9@domain.com"
"User10@domain.com"

Export-CSV Contents


any help is appreciated!

$ignore = @"
User1@domain.com
User4@domain.com
User9@domain.com
User10@domain.com
"@ -split "`r`n"

(Get-Content file.txt  | Select-String -NotMatch -SimpleMatch $ignore) | Out-File file2.txt

As I suppose comparing parts of the line with the email addresses is enough of a match to reliable exclude the unwanted lines. We can make the pattern more restrictive, or switch to your suggestion handling CSV data, if required.

Sorry for the delay, I was on vacation. I tried to add this statement but it's not removing the line from the CSV file. it's just outputing the same exact text file it read back in.

There seems to be an EE issue with the backtick used, I suspect. Let's try something slightly different:
$ignore = 'User1@domain.com',
          'User4@domain.com',
          'User9@domain.com',
          'User10@domain.com'

(Get-Content file.txt  | Select-String -NotMatch -SimpleMatch $ignore) | Out-File file2.txt

Open in new window

]Thank you for the help again. So this time the user was removed but the CSV file structure was manipulated in a way that makes it unusable. For some reason records are now traversing multiple lines in the CSV file.

That has to be an issue with the app you use to read the file. Test with two entries only, and compare the files with a standard editor, then with the app.
