file-copy-cli

A tiny CLI to copy a file from one path to another with a small extension mismatch warning.

Prerequisites

• Node.js 18+ (tested with ESM support)
• npm (comes with Node.js)

Install and Use Locally (no global install)

1. Install dependencies (none, but this ensures node_modules and package-lock exist):

   npm install file-copy-cli

2. Run with npm exec:

   npm exec fcopy <source> <destination>

3. Or use the local binary via npx:

   npx fcopy <source> <destination>

Install and Use Globally

1. Install globally from the project root:

   npm install -g file-copy-cli

2. Now the command fcopy is available everywhere:

   fcopy <source> <destination>

Notes

• The tool warns if source and destination extensions differ; the copy still proceeds.
• Both <source> and <destination> must be valid paths; missing arguments will throw an error.
• Overwrites the destination file if it already exists (default fs.copyFile behavior).

Examples

# Copy using npm exec (local project context)
npm exec fcopy ./notes/todo.txt ./backup/todo.txt

# Using global install
fcopy ./images/logo.png ./public/logo.png

# Using npx without global install
npx fcopy ./data/input.json ./data/output.json
