Write the code to handle command line arguments and execute the desired functionality

[desjoerd-test-bot]

Sure! Based on your requirements, here's a bash script that handles command line arguments and executes the desired functionality:

#!/bin/bash

# Define the function to execute the desired functionality
execute_functionality() {
    # Implement your desired functionality here
    # ...
    echo "Executing the desired functionality..."
    # ...
}

# Parse the command line arguments
while getopts "hf:" opt; do
    case $opt in
        h)
            # Display help message and exit
            echo "Usage: $0 [-f filename]"
            echo "  -f : Specify the filename"
            echo "  -h : Display this help message"
            exit 0
            ;;
        f)
            # Get the filename from the command line argument
            filename=$OPTARG
            ;;
        \?)
            # Invalid option, display error message and exit
            echo "Invalid option: -$OPTARG" >&2
            exit 1
            ;;
    esac
done

# Check if the filename is provided
if [ -z "$filename" ]; then
    echo "Please specify the filename using the -f option."
    exit 1
fi

# Execute the desired functionality
execute_functionality

# Exit the script
exit 0

To create the bash script, you can save the above code in a file with a .sh extension, for example, script.sh. Make sure to give the script executable permissions:

chmod +x script.sh

Then, you can run the script from the command line and pass the desired command line arguments:

./script.sh -f filename.txt

Make sure to replace filename.txt with the actual filename you want to use.
