Dry run to preview changes

$ nomino -r "[regex]" "[output_pattern]" -p

Generate a JSON map of renames

$ nomino -r "[regex]" "[output_pattern]" -g [map.json]

SYNOPSIS

nomino [options] output [source]

nomino is an async batch rename utility for developers. It supports regex-based pattern matching, natural sorting, file extension preservation, dry-run mode, and JSON map generation for documenting rename operations.

PARAMETERS

-r, --regex PATTERN

Regex pattern to match filenames (RE2 syntax).

-s, --sort ORDER

Sort files naturally in ascending or descending order.

-p, --print

Dry run — preview changes without renaming.

-g, --generate FILE

Generate a JSON map of the rename operations.

-e, --extension

Preserve file extensions during rename.

CAVEATS

Uses RE2 regex syntax. Always use dry-run mode (-p) to preview changes before executing.
