I have a line in a csv called examples.
I want to remove that line and every line under it using powershell.  

What is the best way to accomplish this?

Thanks

Your question is not quite clear. Do you have a line called examples in a csv file, or do you have some line in a csv file called examples?
I'm leaning towards the former, so try this:
$InputFile = "C:\Temp\test.csv"
$OutputFile = "C:\Temp\test-NoExamples.csv"
$StopLine = "Examples"
Get-Content $InputFile | % {If ($_ -ne $StopLine) {$_} Else {Break}} | Set-Content $OutputFile

Open in new window

If the latter: is "the line" a regular csv line, and how do you want to identify the line in question; as the full text line, as part of a text line, as properties of the csv columns, ...?

Thanks so much for the fast reply.  I am sorry for my poorly worded question.


I have a large CSV file.   Somewhere down the file will be a Row and in column A row (something)  the word "Examples" will be there.

I want to delete the word examples and every row below that.

Thanks again

If the following doesn't work for you, please provide a csv file (in a 'Code' box or as attachment) you'll be working with (you can of course anonymize the contents).
$InputFile = "C:\Temp\test.csv"
$OutputFile = "C:\Temp\test-NoExamples.csv"
$StopLine = "Examples:"
Get-Content $InputFile | % {If ($_.Trim('"').ToUpper().StartsWith($StopLine.ToUpper())) {Break} Else {$_}} | Set-Content $OutputFile

Open in new window
