Description

Added six new commands to the wand tool:

• Alohomora: Unlocks file or directory permissions, making them writable using chmod.
• Obscuro: Clears the terminal history using history -c.
• Riddikulus: Displays system stats in a humorous way, using tools like figlet, cowsay, and fortune.
• Silencio: Mutes or unmutes the system's sound using amixer.
• Expecto Patronum: Creates a backup of important files to a specified location using cp.
• Reparo: Attempts to repair broken packages or dependencies based on the system's package manager.

Technical details

• Alohomora: Prompts for user confirmation before unlocking file or directory permissions.
• Obscuro: Clears the terminal history and notifies the user about the action.
• Riddikulus: Provides different options for humorous output (cowsay, figlet, and fortune).
• Silencio: Includes an option to unmute the sound with the --unmute flag.
• Expecto Patronum: Supports specifying a custom backup destination.
• Reparo: Detects the package manager and runs appropriate commands for package repair (apt, yum, pacman, or brew).

Tests

1. Alohomora: Tested by changing permissions of different files and directories.
2. Obscuro: Verified that terminal history is cleared as expected.
3. Riddikulus: Tested with different fun options (figlet, cowsay, and fortune).
4. Silencio: Verified both mute and unmute functionality.
5. Expecto Patronum: Tested backup creation to both default and custom locations.
6. Reparo: Tested with different package managers (apt, yum, pacman, and brew).
