## 🛠️ Features

### 🌟 Permission Aliases

Quickly apply common permission settings with pre-defined aliases:

| Alias        | Permissions      | Description                               |
|--------------|------------------|-------------------------------------------|
| `chmod_000`  | `----------`     | No permissions for anyone                 |
| `chmod_400`  | `r--------`      | Read-only for the owner                   |
| `chmod_444`  | `r--r--r--`      | Read-only for everyone                    |
| `chmod_600`  | `rw-------`      | Read/write for the owner                  |
| `chmod_644`  | `rw-r--r--`      | Read/write for the owner, read-only other |
| `chmod_666`  | `rw-rw-rw-`      | Read/write for everyone                   |
| `chmod_755`  | `rwxr-xr-x`      | Full owner, read/execute for others       |
| `chmod_764`  | `rwxrw-r--`      | Full owner, read/write for the group,     |
| `chmod_777`  | `rwxrwxrwx`      | Full permissions for everyone             |

### 🔧 Recursive Confirmation for Permissions

The `change_permission` function allows you to recursively apply permissions
with a confirmation prompt, displaying the number of items affected:

```bash
change_permission 755 /path/to/directory -R
```

### 📂 User, Group, and Others Shortcuts

Fine-tune permissions for specific user groups (owner, group, or others):

| `chmod_u+w`   | Add write permission for the owner         |
| `chmod_u-w`   | Remove write permission for the owner      |
| `chmod_u+r`   | Add read permission for the owner          |
| `chmod_u-r`   | Remove read permission for the owner       |
| `chmod_g+x`   | Add execute permission for the group       |
| `chmod_g-x`   | Remove execute permission for the group    |
| `chmod_g+w`   | Add write permission for the group         |
| `chmod_g-w`   | Remove write permission for the group      |
| `chmod_g+r`   | Add read permission for the group          |
| `chmod_g-r`   | Remove read permission for the group       |
| `chmod_o+x`   | Add execute permission for others          |
| `chmod_o-x`   | Remove execute permission for others       |
| `chmod_o+w`   | Add write permission for others            |
