To convert the recipe name "Slow Cooker Smoky BBQ Chicken Drumsticks" into a more script-friendly format like "Slow_Cooker_Smoky_BBQ_Chicken_Drumsticks", you can use a simple Bash command to replace spaces with underscores. This is a common task when you need to generate filenames or identifiers that require non-spaced strings.

Here’s a straightforward way to do this in Bash, which you can use repeatedly:

Bash Script

Create a script named format_recipe_name.sh with the following content:

#!/bin/bash

# This script converts a recipe name with spaces into a format with underscores

# Input: Recipe name as a string
# Output: Formatted recipe name with underscores

# Function to replace spaces with underscores
convert_name() {
    echo "$1" | sed 's/ /_/g'
}

# Example usage:
recipe_name="Slow Cooker Smoky BBQ Chicken Drumsticks"
formatted_name=$(convert_name "$recipe_name")
echo "Formatted Recipe Name: $formatted_name"

How to Use the Script

1. Make the Script Executable: Open your terminal and run the following command to make your script executable:

   chmod +x format_recipe_name.sh
   

2. Run the Script: You can now run the script by typing:

   ./format_recipe_name.sh
   

   This will output the formatted name: Slow_Cooker_Smoky_BBQ_Chicken_Drumsticks.

Modifying the Script for General Use

If you want to use the script for any recipe name, you can modify it to accept an input argument:

#!/bin/bash

# Function to replace spaces with underscores
convert_name() {
    echo "$1" | sed 's/ /_/g'
}

# Check if an argument is provided
if [ $# -eq 0 ]; then
    echo "Usage: $0 'recipe name'"
    exit 1
fi

# Convert and output the formatted name
formatted_name=$(convert_name "$1")
echo "Formatted Recipe Name: $formatted_name"

Now, you can pass any recipe name as an argument to the script:

./format_recipe_name.sh "Slow Cooker Smoky BBQ Chicken Drumsticks"

This flexible script can handle any name you provide, making it easy and repeatable for different recipes or other similar formatting needs.
