1. Manual Installation: Installing Pandoc using package managers.
2. Automated Installation: Using a Bash script to check for Pandoc and install it if necessary.

2. Automated Installation Script

Instead of manually installing Pandoc, you can use the following Bash script to check for Pandoc and install it automatically based on your OS.

Installation Script:

Save the following script as install-pandoc.sh:

#!/bin/bash

# Function to check if a command exists
command_exists() {
    command -v "$1" >/dev/null 2>&1
}

# Check if Pandoc is installed
if command_exists pandoc; then
    echo "Pandoc is already installed: $(pandoc --version | head -n 1)"
    exit 0
fi

echo "Pandoc is not installed. Attempting to install it..."

# Detect the package manager and install Pandoc
if [[ -f /etc/debian_version ]]; then
    # Debian-based (Ubuntu, Debian)
    sudo apt update && sudo apt install -y pandoc
elif [[ -f /etc/arch-release ]]; then
    # Arch Linux
    sudo pacman -Syu --noconfirm pandoc
elif [[ "$(uname)" == "Darwin" ]]; then
    # macOS
    if command_exists brew; then
        brew install pandoc
    else
        echo "Homebrew is not installed. Please install Homebrew first: https://brew.sh/"
        exit 1
    fi
else
    echo "Unsupported operating system. Please install Pandoc manually: https://pandoc.org/installing.html"
    exit 1
fi

# Verify if the installation was successful
if command_exists pandoc; then
    echo "Pandoc successfully installed: $(pandoc --version | head -n 1)"
else
    echo "Pandoc installation failed. Please try installing it manually."
    exit 1
fi

Running the Script

To execute the script, follow these steps:

1. Make the script executable:

   chmod +x install-pandoc.sh

2. Run the script:

   ./install-pandoc.sh

The script will check if Pandoc is installed and install it using the appropriate package manager.
