Window batch script to truncate leading zeros in a text file and write to a new file

Question

Kindly help with a windows batch script that will remove the leading zeroes in a text file and write to a new file without the zeroes.

Input file format

Output format

Thank you.

i tried with script but am only able to write the last on the file onto the new file. @ECHO OFF &SETLOCAL ENABLEDELAYEDEXPANSION ::Extract only the first 5 characters FOR /f "delims=" %%a IN (%1) DO ( SET "var1=%%a" ) ECHO %var1:~1,9%>max_test.txt — user3798582, Jul 02 '14 at 19:29
put the last `)` to the very end (after max_test.txt) to include the echo into the loop. — Stephan, Jul 02 '14 at 19:43

@echo off
(for /f "tokens=* delims=0" %%a in (inputFile) do echo(%%a)>outputFile

This uses the hability of for /f to split a string in tokens, removing the delimiters used for the splitting. As the 0 is used as delimiter, but we are asking for all the string in only one token, for will discard initial delimiters until the first token is found, resulting in leading zeroes removed.

This uses a helper batch file called repl.bat (by dbenham) - download from: https://www.dropbox.com/s/qidqwztmetbvklt/repl.bat

Place repl.bat in the same folder as the batch file or in a folder that is on the path.

@echo off
type file.txt | repl "^0*" "" >newfile.txt 
pause
