Import-Csv Select -Skip - powershell

Question

I have multiple CSV files that need to be merged to one. In every single CSV file there is a header and in the second row some text that I don't need.
I noticed the | Select -Skip 1 statement for the headers. Now I was wondering how I can skip the 3rd row?
I tried this, but this gives me an empty file
Get-ChildItem -Path $CSVFolder -Recurse -Filter "*.csv" | %{
Import-Csv $_.FullName -Header header1, header3, header4 |
Select -Skip 1 | Select -Skip 2
} | Export-Csv "C:\Export\result.csv" -NoTypeInformation

Answer 1

Select-Object doesn't allow you to skip arbitrary rows in between other rows. If you want to remove a particular row from a text input file, you can do so with a counter, e.g. like this:
$cnt = 0
Import-Csv 'C:\path\to\input.csv' |
Where-Object { ($cnt++) -ne 3 } |
Export-Csv 'C:\path\to\output.csv' -NoType
If the records in your input CSV don't have nested line breaks you could also use Get-Content/Set-Content, which is probably a little faster than Import-Csv/Export-Csv (due to less parsing overhead). Increase the line number you want to skip by one to account for the header line.
$cnt = 0
Get-Content 'C:\path\to\input.csv' |
Where-Object { ($cnt++) -ne 4 } |
Set-Content 'C:\path\to\output.csv'

Answer 2

try this
$i=0;
import-csv "C:\temp2\missing.csv" | %{$i++; if ($i -ne 3) {$_}} | export-csv "C:\temp2\result.csv" -NoTypeInformation

Answer 3

If all you are doing si skipping the first the rows in all user cases, just use -skip 3.
Get-Content -Path 'D:\Temp\UserRecord.csv'
# Results
<#
