What are alternatives to best practices in bash scripting?

Bash scripting can be enhanced through various alternatives to traditional best practices. Utilizing different approaches can lead to more efficient, readable, and maintainable scripts. Here are some notable alternatives you might want to consider:

Use of Functions: Instead of writing all code in a linear fashion, consider breaking your script into functions. This promotes reusability and better organization.
Embrace Associative Arrays: For handling related data, associative arrays provide a more structured way than using simple positional arrays.
Use of Here Documents: This allows for more readable multiline input in commands, making scripts cleaner.
Prefer `[[` over `[`: The `[[` command offers more features (like regex matching) and prevents word splitting and pathname expansion.
Logging: Instead of just outputting to stdout, utilize logging practices to capture errors and output for review.

Here’s a simple example demonstrating the use of functions and associative arrays in a bash script:


        #!/bin/bash

        declare -A user_data
        user_data["Alice"]="alice@example.com"
        user_data["Bob"]="bob@example.com"

        function print_user_info {
            username=$1
            echo "User: $username, Email: ${user_data[$username]}"
        }

        for user in "${!user_data[@]}"; do
            print_user_info $user
        done
