Powershell add file name to text file

Question

I am currently writing a script that consolidates all of the contents of several text files into one file. I would like to (if possible), write into the file, the name of the file above the contents from that file.

Example:

Textfile1.txt

ContentContentContent
ContentContentContent

Textfile2.txt

ContentContentContent
ContentContentContent

Textfile3.txt

ContentContentContent
ContentContentContent

Is this possible?

Can you provide more details, preferably some sample code, showing how you are grabbing the list of file names and writing them out? The answer really depends on how you are currently doing things. — David Anderson

Yep, it's not too hard at all. We get a listing of the files we want using the Dir command, then we pipe that into ForEach to run a {scriptblock}. We'll then build a $variable to create the blob of text that we'll add to our existing file (Output.txt).

We can use the $_ variable to pull out the FileName property, and then use the Get-Content cmdlet to grab the text of the file, giving us the fields you wanted. We join them both with the `n NewLine character. The end result, is this:

dir *.txt | ForEach {
    $variable = "$($_.Name)`n$(Get-content $_.FullName)"
    Add-Content -Value $variable -Path .\Output.txt
}

Which gives us an output like this:

TextFile1.txt
ContentContentContent ContentContentContent
TextFile2.txt
ContentContentContent ContentContentContent
TextFile3.txt
ContentContentContent ContentContentContent

Please note that dir is an alias for Get-ChildItem and ForEach is an alias for ForEach-Object. Clarification required if the OP wants single line or multiline input from the file contents.
