How to remove Linefeed (LF) from first row in a text file using a batch file

Question

I needed a script to remove the linefeed from the first row of a text file.

Other - similar topics I've researched were confusing, and had many irrelevant or misleading responses,

the way I used to get the first row (NOTE: i have not tested if this also removes other hidden chars, but I was advised it does- like CR, so please be aware) content and also remove the linefeed(=LF character) on Windows-command prompt/batch file/CMD/command is:

  for /F "delims=" %%i in (source_file.txt) do (  
      <nul (set/p z=%%i) >outputfile.txt
      goto BREAK1
    )
    :BREAK1

Immidiately Under :BREAK1 row, you continue working on with a LineFeed free outputfile.txt

Yes, but that will remove the newline character as well. – SomethingDark Mar 21 '17 at 11:16
@SomethingDark yeah, that was the purpose of "How to remove Linefeed (LF)" . I was aiming to remove the newline (A.k.a LF/ Line Feed) – Dror Mar 23 '17 at 08:58
I meant carriage return... no idea why I said line feed. – SomethingDark Mar 23 '17 at 11:03
@SomethingDark lol. Thanks, i'm adding a comment that this also has potential to remove other hidden characters, not just the linefeed – Dror Mar 23 '17 at 20:11

If you only need the first line, reading with set /p is simpler than a FOR/F loop.

setlocal EnableDelayedExpansion
set /p line= < source_file.txt
<nul set /p ".=!line!" > outputfile.txt
