Question 1

How do I use regex to rename files with nomino?

Accepted Answer

Use the -r option with a Rust regex pattern, e.g., `nomino -r "(\d+)_" "file_{1}.txt"` to capture digits. The Capture Groups section in the README explains named groups and placeholders for output formatting.

Question 2

Nomino vs traditional rename command: which is better for developers?

Accepted Answer

Nomino excels with advanced features like Rust regex and JSON mapping, making it superior for complex, scriptable renames. Simple rename commands might suffice for basic string replacements without patterns.

Question 3

How to pad numbers in filenames, like turning 1 into 001?

Accepted Answer

Use placeholders with padding, e.g., {1:3} for the first capture group padded to three digits. The Placeholders section details how {G:P} syntax works, including handling of non-numeric values.

Question 4

Does nomino rename files in subdirectories or only the current folder?

Accepted Answer

It can handle subdirectories using options like --depth and --max-depth, but by default, it operates on files in the specified directory set with -d or the current path.

Question 5

Is nomino safe to use without losing files?

Accepted Answer

Always run with --dry-run first to preview changes. Since there's no undo, backup your files before executing renames to prevent accidental data loss from regex errors or typos.

Question 6

How to create and use a JSON map file for batch renaming?

Accepted Answer

Generate a map with -g after renaming, or create a JSON file manually with old-new name pairs. Use -m or --from-file to apply it, enabling reproducible renaming workflows.
