Global Command Setup (Run from Anywhere)

Set up a global sarthi-lab command that works from any terminal directory.

macOS / Linux

Symlink Setup

# Make script executable
chmod +x launch.sh

# Create global symlink (requires sudo)
sudo ln -s "$(pwd)/launch.sh" /usr/local/bin/sarthi-lab

If /usr/local/bin isn't in PATH, add it:

echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.bashrc  # or ~/.zshrc
source ~/.bashrc

Windows

Add to PATH

1. Copy launch.bat to a directory already in PATH:

   • C:\Windows\System32
   • C:\Program Files\Git\usr\bin (if Git installed)

2. OR add repo to PATH:

   • Open System Properties → Environment Variables
   • Edit User variables → PATH
   • Add C:\path\to\sarthi_lab
   • Restart terminal

Troubleshooting

Issue	Solution
sudo: command not found (mac/Linux)	Use ~/bin: ln -s "$(pwd)/launch.sh" ~/bin/sarthi-lab
Permission denied (symlink)	Ensure /usr/local/bin exists and is writable
Windows PATH not working	Use full path: C:\path\to\sarthi_lab\launch.bat
npm run dev fails	Check Node.js ≥18, run npm install
Exercises not loading	Ensure you're using dev mode (npm run dev); packaged DMG may have issues
