Fix Git Repository Ownership and Permissions

This compound command performs two critical operations:

1. Ownership Change (chown -R $(whoami):$(whoami) .git)

   • Changes both user and group ownership of the entire .git directory tree
   • $(whoami) dynamically gets the current username
   • -R flag applies changes recursively to all subdirectories and files

2. Permission Setting (chmod -R ug+rwx,o+rx .git)

   • ug+rwx: Grants read, write, and execute permissions to user and group
   • o+rx: Grants read and execute permissions to others (no write access)
   • -R flag applies permissions recursively

Common Use Cases:

• After cloning a repository with sudo
• When Git operations fail with "Permission denied" errors
• After accidentally running Git commands as root
• When switching between different user accounts on the same repository
• Resolving issues after copying repositories between systems

Example Scenarios:

# When you see errors like:
# fatal: could not lock config file .git/config: Permission denied
# error: insufficient permission for adding an object to repository database

# Run the fix command:
sudo chown -R $(whoami):$(whoami) .git && sudo chmod -R ug+rwx,o+rx .git

# Then verify with:
ls -la .git/

• Always run this command from the repository root directory
• Verify you're in the correct directory before execution
• The command uses sudo, so ensure you understand the implications
• Consider backing up important repositories before making permission changes
