Batch: delete line feed from end of text file?

Question

I have a .txt file where I need to get rid of the last line feed. Looking at the file in a HEX Editor it shows "0d 0a" at the end.

I have looked at the thread How to delete Linefeed using batch file but that did not help. I have tried COPY source target /b which also does not help.

Unfortunately I can't use Java or any third party tools, I need to use a batch file.

How can I get rid of that line feed at the end?

Answer 1

Using batch this should work.

@echo off
setlocal DisableDelayedExpansion
set "firstLineReady="
(
    for /F "eol=$ delims=" %%a in (myFile.txt) DO (
        if defined firstLineReady (echo()
        set "firstLineReady=1"
        <nul set /p "=%%a"
    )
) > out.txt

It copies all lines and append to each line a CR/LF, but not to the last one
