You never mentioned your OS this but may work:

Code: [Select]@echo off
setlocal enabledelayedexpansion
SET count=0
for /f "tokens=* delims=" %%i in (data.txt) do (
set /a count=%count%+1
if not !count!==1 echo %%i >> data1.txt
)

Text files do not allow in-place deletes; you MUST create a SEPARATE output file.

Quatroking has a point. Run this enough times and you'll run out of lines to delete. Quote

can you provide a use case for this? from what i see, it SEEMS your intention is to delete all the lines of the file? if it is, just
Code: [Select]
type nul > yourfile.txt
will do. This will blank out your file. I may be wrong though
