🏗 Homebrew Installation¶

Automated installation of Homebrew on macOS and Linux. The script checks if Homebrew is already installed, installs it if necessary, and sets up the shell environment.

🛠️ Service Configuration¶

• Detects the operating system (macOS or Linux)
• Installs Homebrew if not already present
• Updates the shell profile (.zprofile or .profile)
• Skips installation if Homebrew is already installed
• Provides user feedback in German

1. → Prevents the use of the Homebrew API for installation and enforces the classic installation method. Recommended for compatibility and stability.
2. → The script automatically adds the Homebrew environment to the appropriate profile depending on the OS: macOS: .zprofile, Linux: .profile

🔐 Important Notes¶

• The script requires write permissions to the user's profile file
• Unsupported systems will abort with an error
• Homebrew should be available in the current terminal after installation

🚀 Usage¶

sh assets/scripts/brew.sh

• On macOS, .zprofile is updated and the Homebrew environment is loaded
• On Linux, .profile is updated and the Homebrew environment is loaded

🔄 Maintenance & Updates¶

• To update Homebrew:
  

  brew update && brew upgrade
  

• To rerun the script, simply execute as described above
