[Discussion] I am working on a curated, cross-distro library of interactive command templates. What are your pacman, apt, dnf, or zypper essentials?

Hello everyone.

I’m currently working on an open source project to help terminal users organise and reuse simple and complex one-liners.

While the engine is almost ready for its next major release this Friday, I’ve realised that my personal library is far too biased towards Arch Linux.

I would like to put together a truly universal, verified collection of "Problem -> Solution" command templates for every major distribution.

Whether you use Arch, Debian, Fedora, openSUSE, or even macOS, what are the 3-5 commands you find yourself using most for system maintenance, networking, or development?

I’m specifically looking for:

Package Management: Beyond the basics. Think cleanup, dependency checks, or kernel stubs.

Obscure One-Liners: That find or sed string you spent an hour perfecting and now use every week.

Interactive Snippets: Commands that require variables (IPs, filenames, usernames).

Please post your command, its description, and which distro/environment it belongs to.

Simple and complex examples I am looking for:

sudo dnf autoremove -> [Fedora] Clean up orphaned packages and unused dependencies.

sudo zypper dup --dry-run | grep -iP '({{package_name}}|upgrading|removing)' -> [openSUSE] Perform a distribution upgrade simulation and filter for specific package impacts.

sudo apt-mark showmanual | grep -vP '^(ubuntu-desktop|gnome-desktop)' | xargs -r sudo apt-get purge -y {{package_name}} -> [Debian/Ubuntu] Identify manually installed packages and purge a specific one along with its configuration files.

sudo dnf history list {{package_name}} && sudo dnf history rollback {{transaction_id}} -> [Fedora] View the specific transaction history for a package and rollback the system to a previous state.

nmap -sP {{network_range}} && nmap -p {{port}} --open {{target_ip}} -> [Universal] Perform a ping sweep on a range, then scan a specific target for an open port.

find {{path}} -type f -exec du -Sh {} + | sort -rh | head -n {{count}} -> [Universal] Find and rank the top X largest files in a specific directory tree.

I’m aiming to have these verified and added to the official vaults in time for the release this Friday. Your help in making this a comprehensive resource for the community would be greatly appreciated!
