A Node.js command-line tool that generates secure random passwords and automatically copies them to your clipboard.

This application generates random passwords by:

1. Creating Character Sets: Builds a pool of characters including:

• Uppercase and lowercase letters (A-Z, a-z) - always included
• Numbers (0-9) - optional, included by default
• Symbols (!@#$%^&*_-+=) - optional, included by default

2. Random Generation: Randomly selects characters from the pool to create a password of your specified length

3. Clipboard Integration: Automatically copies the generated password to your system clipboard for easy pasting

4. Optional Persistence: Can save generated passwords to a local passwords.txt file with the -s flag

• commander.js - Handles command-line interface and options parsing
• chalk - Provides colored terminal output for better readability
• clipboardy - Enables cross-platform clipboard access

Install dependencies:

npm install

Run directly with Node.js:

node index.js [options]

Create a global symlink to run passgen from anywhere:

npm link

# Now you can run from any directory
passgen [options]

# To remove the global command
npm unlink

# Generate an 8-character password (default)
passgen

# Generate a 16-character password
passgen -l 16

# Generate a password without numbers
passgen --no-numbers

# Generate a password without symbols
passgen --no-symbols

# Generate a 12-character password with only letters and numbers
passgen -l 12 --no-symbols

# Generate a password and save it to passwords.txt
passgen -s

# Combine multiple options
passgen -l 20 -s --no-symbols

When you run the command, you'll see:

• The generated password displayed in blue
• A confirmation message that the password was copied to clipboard
• If -s flag is used, a confirmation that the password was saved
