This script creates a spreadsheet (packages.csv) listing every software package manually installed on a Linux system, along with its executable commands and a brief description.

echo 'Package,Commands,Description' > packages.csv

for pkg in $(apt-mark showmanual); do
    desc=$(dpkg-query -W -f='${Description}' "$pkg" 2>/dev/null | head -n1)

    cmds=$(dpkg -L "$pkg" 2>/dev/null \
        | grep -E '/bin/' \
        | xargs -r -n1 basename \
        | sort -u \
        | paste -sd ';' -)

    printf '"%s","%s","%s"\n' \
        "$pkg" "$cmds" "$desc" >> packages.csv
done
