[FIXED] What is the fastest way to retrieve the header names from csv files

Issue

I am trying to organize the column names by retrieving the unique header names of the csv files.

I used the following the code to retrieve the header names, but this script response is not fast when I have large size or millions of csv files in directories & subdirectories.

$files = Get-ChildItem "F:\MY_DATA\ASUSH" -Recurse
foreach ($f in $files) {
if ($f -Like "*.csv") {
  echo $f.FullName
  $Data=Get-Content -Path $f.FullName
  echo $Data[0]
}
}

What is the fastest way to retrieve the csv file header names?

Solution

Get-Content has a -TotalCount parameter that will only read a certain number of lines.

$Data = Get-Content -Path $f.Fullname -TotalCount 1

That should speed things up.
