How to replace linefeed into nothing using repl.bat in a BATCH file

Question

Im trying to use REPL.BAT to delete the linefeed found in the file.

Now I have this code

Type "C:\user\AllFiles\%%a.in.tmp"  | C:\user\bat\repl.bat "%%s" "%%t" X > "C:\user\AllFiles\%%a.out.tmp"




%%s - Can be found in the first column of replace.txt
%%t - Can be found in the second column of replace.txt

Note that that below example matches pattern starts with AAA+any 3 chars and replaced with XXXYYY

AAA\d{3}     XXXYYY

Now how will I implement replacing the \R with NULL?

Null is usually `\0`. I guess you mean replace with nothing ? For windows files, the regex would be find `(?:\r\n)+` replace with `nothing`. Alternatively the regex could be `(?:\r?\n)+`. You mean line-breaks right? — , Nov 18 '14 at 18:01
@sln Yes replace nothing. So what will be my parameter for column1 and 2 in replace.txt? — PeterS, Nov 18 '14 at 18:04

LineBreaks

filter fix {lf|cr}

Fixes problems with line endings.

Lines are broken at the line feed character. If preceded by a carriage return both are removed. However a single carriage return without a line feed does not break the line.

cr - removes all stray CR and LF left on each line.

lf - add a LF to any CR embeded in the middle of the line.

It then writes the line with a CRLF at the end (the writeline method adds it).

Example Fixes win.ini, not that it needs fixing, and sends it to the screen

filter fix cr <"%systemroot%\win.ini"

You'll have to modify script as it expects command line arguments.

Set Arg = WScript.Arguments
set WshShell = createObject("Wscript.Shell")
Set Inp = WScript.Stdin
Set Outp = Wscript.Stdout

    If Arg(1) = "cr" then 
        Do Until Inp.AtEndOfStream
            Line=Inp.readline
            Line=Replace(Line, vbcr, "")
            Line=Replace(Line, vblf, "")
            outp.writeline Line
        Loop
    End If
    If Arg(1) = "lf" then 
        Do Until Inp.AtEndOfStream
            Line=Inp.readline
            Line=Replace(Line, vbcr, vbcrlf)
            outp.writeline Line
        Loop
    End If

To use you need to run with cscript.

cscript //nologo c:\scriptname.vbs fix cr <inputfile.txt >outputfile.txt

I'm sure you can modify it. Regular Expressions are overkill for this.

You have not provided enough information for anyone to provide the full answer.

In general, you must use the M (multi-line) option if you want to manipulate \n (linefeed).

The following will remove all \r\n and/or \n from a file. Adapt as needed.

type file.txt|repl "\r?\n" "" m >out.txt
