# [ `fxtools unique` ]
## Summary
This is a command that will determine all unique sequences within a fastx file and split the records into either unique or duplicates.
It will also count the number of unique/duplicate sequences/duplicate records and report those.

Nulled reads will not be reported by default but can be written to a filepath with the `-n` flag.

```bash
fxtools unique \
-i <input_fastx> \
-o <optional_output_file_for_unique> \
-n <optional_output_file_for_null>
