🛠️ Mac Terminal Guide: Find & Completely Remove Installed Apps (npm & Homebrew)

My personal cheat sheet for finding, uninstalling, and completely removing apps installed via Terminal on macOS.

📌 Step 1: Find Where the App Is Installed

Replace appname with the application name (example: codex, yarn, pnpm, etc).

command -v appname which appname type -a appname

Example:

command -v codex which codex type -a codex

📌 Step 2: Check if Installed via Homebrew

Search installed formulas:

brew list | grep appname

Get detailed information:

brew info appname

📌 Step 3: Check if Installed via npm

npm list -g --depth=0 | grep appname

Example:

npm list -g --depth=0 | grep codex

📌 Step 4: Remove the App

🍺 Remove from Homebrew

brew uninstall appname

If installed as a cask:

brew uninstall --cask appname

📦 Remove from npm

npm uninstall -g appname

Example:

npm uninstall -g @openai/codex

📌 Step 5: Clear Shell Cache

Sometimes Terminal still thinks the app exists after uninstalling.

hash -r

📌 Step 6: Verify That the App Is Gone

command -v appname || echo "✅ App removed successfully"

📌 Step 7: Search for Leftover Files

find ~/.appname /opt/homebrew -iname "*appname*" 2>/dev/null

Example:

find ~/.codex /opt/homebrew -iname "*codex*" 2>/dev/null

📌 Step 8: Remove Leftover Files

⚠️ WARNING: Double-check before running rm -rf!

rm -rf ~/.appname rm -rf /opt/homebrew/.appname

Example:

rm -rf ~/.codex rm -rf /opt/homebrew/.codex

📌 Step 9: Final Verification

hash -r command -v appname type -a appname

If nothing is returned, the application has been completely removed from the system.

🚀 Quick Checklist

# Find executable command -v appname which appname type -a appname # Check Homebrew brew list | grep appname brew info appname # Check npm npm list -g --depth=0 | grep appname # Uninstall brew uninstall appname brew uninstall --cask appname npm uninstall -g appname # Clear cache hash -r # Search leftovers find ~/.appname /opt/homebrew -iname "*appname*" 2>/dev/null # Remove leftovers rm -rf ~/.appname rm -rf /opt/homebrew/.appname # Final check command -v appname type -a appname
