## 4️⃣ Disk Space Checker for macOS
This is a simple shell script designed for macOS to monitor available disk space on your main volume (`/`) and provide a visual alert if it falls below a customizable threshold.
### 📥 Installation
#### Download the Script:
- Clone this repository or download `disk_space_checker.sh` directly:
bash
git clone https://github.com/yourusername/your-repo.git
cd your-repo
#### Make It Executable:
Run the following command in your Terminal to make the script executable:
bash
chmod +x disk_space_checker.sh
Optional: Move to a Bin Directory. For easy access, move it to a directory in your $PATH, like /usr/local/bin:
bash
mv disk_space_checker.sh /usr/local/bin/disk_space_checker
Now you can run it from anywhere by typing disk_space_checker.
### 🚀 Usage
Run the Script:
Execute the script from its location:
bash
Wrap
Copy
./disk_space_checker.sh
Or, if you moved it to a bin directory:
bash
Wrap
Copy
disk_space_checker
#### Example Output:
When disk space is sufficient:
text
Disk space looks good!
45 GB available out of 250 GB.
Usage: [========= ] 18%
When disk space is low:
text
WARNING: Low disk space!
8 GB available out of 250 GB.
Consider freeing up some space.
Usage: [= ] 3%
#### Customize the Threshold:
Open the script in a text editor (e.g., nano disk_space_checker.sh).
Adjust the THRESHOLD variable (default is 10 GB):
bash
THRESHOLD=20 # Change to 20 GB
#### ⚙️ Features
- Color-Coded Alerts: Green for sufficient space, red and yellow for low space warnings.
- Customizable Threshold: Set your own low-space limit by editing the THRESHOLD variable.
- Visual Progress Bar: Displays a simple bar showing the percentage of used disk space.
- Error Handling: Checks for valid disk space data and exits gracefully if retrieval fails.
- Lightweight: No dependencies beyond standard macOS tools (df, bash).
