A simple command-line helper I use very often. Recursively loop through all files in the specified directory and its subdirectories, wrapping their contents in triple backticks. Clipboard automation with `xclip`.

gptfiles.sh

#!/bin/bash

function process_directory {
    for file in "$1"/*; do
        if [ -d "$file" ]; then
            process_directory "$file"
        elif [ -f "$file" ]; then
            /bin/cat << EOF

${file}:
\`\`\`
$(cat "${file}")
\`\`\`
EOF
            if command -v xclip >/dev/null 2>&1; then
                cat "${file}" | xclip -selection clipboard
                echo "Copied ${file} contents to clipboard"
            else
                echo "xclip is not installed. Please install xclip to enable clipboard copying."
            fi
        fi
    done
}
