I have a very big file which contains ~XXX as delimiter. For every occurence of that string I need to start from newline.I need a windows batch file

example :12312312312312@XXXqewqweqweqweqweqweqweqwe@XXX123KJFLKJSFLKJ@XXXsfdsdf

OutPut:

12312312312312
@XXXqewqweqweqweqweqweqweqwe
@XXX123KJFLKJSFLKJ
@XXXsfdsdf

Appreciate your response.

Thanks NK

    Is the leading colon part of the example or a mistake? Is it `~XXX` or `@XXX` ? What code have you written so far, where did you get stuck? [SO] isn't a script writing service. –  May 10 '17 at 22:11

    What scale is a very big file for you? Batch processing is limited by maximum cmdline length. –  May 10 '17 at 22:19

PowerShell may be better suited to the task, a minimal example:

> "12312312312312@XXXqewqweqweqweqweqweqweqwe@XXX123KJFLKJSFLKJ@XXXsfdsdf" -replace '@XXX', "`n@XXX"
12312312312312
@XXXqewqweqweqweqweqweqweqwe
@XXX123KJFLKJSFLKJ
@XXXsfdsdf

There are ways to read from file in chunks or use a streamreader.
