Setup as a Global Command:

For macOS and Linux Users

Move the Binary File and Set Execution Permissions:

sudo mv leetcode-setup /usr/local/bin/ &&
sudo chmod +x /usr/local/bin/leetcode-setup

For Windows Users

  1. Create a Directory:

    • Create a directory where you will store the binary. Recommended locations are C:\Tools or C:\Users\YourUsername\bin.

  2. Move the Binary File:

    • Move the leetcode-setup.exe file into the directory you created.

  3. Add the Directory to the PATH:

    • Right-click on "This PC" or "My Computer", and select "Properties".
    • Click on "Advanced system settings".
    • In the "System Properties" window, click on "Environment Variables".
    • In the "System variables" section, find and select the "Path" variable, then click on "Edit".
    • In the "Edit environment variable" window, click "New" and enter the path to your directory, e.g., C:\Tools.
    • Click "OK" to save the changes.
