Nom is a minimalist bulk renamer for the command line. It's a faster, more colorful, and enhanced version of the simple rn tool.
It provides several methods to batch-process file names: convert to lowercase, uppercase, snake_case, dash-case, or add sequential numbering. Extensions are automatically preserved and lowercased.
Ensure you have Go installed. Run the following command in the project directory:
go build -o nom main.goTo use nom from anywhere, move the binary to your local bin directory (usually /usr/local/bin for manual installs):
sudo mv nom /usr/local/bin/nom <method><path> [options]| Method | Alias | Description |
|---|---|---|
lower | lc | Convert filename to lowercase. |
uppercase | uc | Convert filename to uppercase. |
dasherize | dash | Convert to lowercase with dashes (-). |
snakeify | sn | Convert to lowercase with underscores (_). |
spacify | sp | Convert to lowercase with spaces. |
ucwords | ucw | Uppercase the first letter of each word. |
number | num | Rename with sequential numbering. |
