How do I set the range?

Pass --batch as START,END, for example 1,10 to extract items 1 through 10 from the file or folder.

Do I have to choose --mode?

No. It auto-detects lines versus files from the input. Force one with --mode lines or --mode files when needed.

Which flags select the source input?

Use --file for lines mode and --folder for files mode. Pair either with --batch START,END.

Does this node scan or probe hosts?

No. It only extracts a batch. Wire the FILE or FOLDER output into nuclei, httpx, or another consumer.

What does the node write?

A file and a folder holding the selected slice. Feed that into the scanner or prober that should consume one batch at a time.

overview

What batch-output-v2 does

batch-output-v2 is the fan-out slicer for large lists and folders. In lines mode it cuts a START,END span from a file; in files mode it cuts a span from a folder's sorted file list.

Operators use it when one serial pass over a huge target set will not finish. Pass --batch as START,END (for example 1,10) and run parallel copies of the downstream scanner on each range.

Omit --mode to auto-pick from the input you supplied (--file or --folder). The managed node writes FILE and FOLDER holding the selected slice for the next consumer.

use cases

Where batch-output-v2 fits

Fan a big list out across parallel nodes

Split a large file into START,END line ranges and feed each to its own copy of a scanner so the run finishes faster than one serial pass.

Batch a folder of inputs

Use files mode to extract a range from a sorted folder so a downstream node processes inputs in groups instead of all at once.

Let the tool pick the mode

Hand it a file or a folder and rely on auto-detection to choose lines or files mode when inputs vary across runs.

Keep heavy runs inside limits

Process one batch at a time through an expensive node to stay within time and resource budgets on very large datasets.

Name	Type	Flag	Description
file	FILE	--file	Input file for lines mode (extract line range from this file).
folder	FOLDER	--folder	Input folder for files mode (extract file range from sorted file list).
batch	STRING	--batch	Batch range as START,END (e.g., "1,10" extracts items 1 through 10).
mode	STRING	--mode	Processing mode: 'lines' (extract lines from file) or 'files' (extract files from folder). Auto-detects if not specified.

guidance

Choosing batch-output-v2

Use batch-output-v2 to split a file or folder into ranges for parallel processing. Prefer it over batch-output for new graphs. It slices input; it runs no scanner. Place it ahead of the consumer you want to fan out.

batch-output

Original line-range slicer. v2 adds explicit modes, folder support, and parallel processing.

duplicut

Deduplicates large lists. Shrinks the input rather than slicing it into batches.

anew

Appends only new lines. Different list utility for tracking novelty across runs.

faq

batch-output-v2 questions

v2 adds explicit lines and files modes, folder batching, mode auto-detection, and parallel batch handling on the same range idea.

Run batch-output-v2 yourself

A large target list feeds batch-output-v2, which extracts a START,END batch and passes it to nuclei so scanning runs on one parallelizable chunk.
