batch remove <CR><LF> from last line only in text file
I have script which works fine as I expected it remove <CR><LF> from last line only in text file. But if there is space or tab in record it skips everything. So I want to remove only last line CR CF. Given scripts scans all lines from target text file, removes blank lines (I don't want this. Only scan last line and remove CR CF) and append into destination file.
bcp TRDS.dbo.tbltestExtracts out "C:\Data\CAAGIndividualsFile.TXT" -c -testinstance\T_GSS -Utest -Ptest
call :StripBlankLines CAAGIndividualsFile.TXT
rem del CAAGIndividualsFile.TXT
rem ren temp_CAAGIndividualsFile.TXT CAAGIndividualsFile.TXT
goto :eof
:StripBlankLines
For %%x in ("%~1") do set OutF=temp_(%%~nx).txt
if exist "%OutF%" del "%OutF%"
set FirstLine=1
for /F "usebackq delims=" %%B in (%*) do (
call :TrimWS %%B
if not "!Line!"=="" (
if "!FirstLine!"=="1" (
set FirstLine=0
) else (
>>"%OutF%" echo.
)
call :write !Line!
)
)
goto :eof
:TrimWS
set Line=%*
goto :eof
:write
>>"%OutF%"<NUL set /p Dummy=%*
goto :eof ASKER CERTIFIED SOLUTION

@oBdA: Thank you Sir. It seems working... Thank you again 500*4
The issue with that file is that there's a NUL (ASCII 0) in the first line of that file (check it in a hex editor or in something like Notepad++ with "Show all characters" enabled).
This character shouldn't appear in a text file at all, so you need to check your database how it slipped into a text field in the first place and then made its way into an export.
You can expect all kinds of strange behavior when trying to modify a "text" file that contains non-printable characters other than TAB/CR/LF.
The first line looks like actually like this:
