+# Remove Empty Lines from Text File
+
+This Python script removes empty lines from a text file using command-line arguments. 
+
+## Usage
+
+1. Run the script with:
+
+   ```
+   python remove_empty_lines.py input_file output_file
+   ```
+
+   Replace `input_file` with the input file path and `output_file` with the output file path.
+
+2. The script processes `input_file`, removes empty lines, and saves the result in `output_file`.
+
+## Example
+
+```shell
+python remove_empty_lines.py input.txt output.txt
+```
+
+This command processes `input.txt` and saves the cleaned content to `output.txt`.
+
+## Error Handling
+
+- Handles incorrect usage with a usage message and exit.
+- Gracefully handles file not found errors and other exceptions, providing informative messages.
