tealdeer takes up 3.7MB on my system. It's a rust implementation of tldr - simplified man pages with practical examples. If I want to do some common thing with a program I don't use very often, chances are I can type (e.g.) tldr kill and it'll tell me what I need to know.

gnumeric runs great on any old linux machine - it isn't as sophisticated as Libreoffice Calc but for basic spreadsheeting, it's very fast and lightweight.

gnucash is an alternative to quickbooks for accounting - it's been around so long that it will run on anything and it does the job without sharing your data or bombarding you with ads.

you can always run nmap in the terminal and have some fun with that.

jq for parsing/formatting/manipulating JSON, and its yq wrapper for YAML. Holy shit you can do powerful queries with them.

yt-dl for videos

and gallery-dl for pictures good stuff

In no particular order (although I think 'lightweight' is arbitrary):

• lsd

cool-retro-term for all your old-school CRT needs. 1.8M executable.

I recently switched to micro from nano, and so far I'm really liking it.

• Dialect for translation. Flathub link
• Image Roll for viewing images. It's faster than most image viewers, especially on slow devices. Flathub link
• Quick Lookup for finding the meaning of a word on Wiktionary. Flathub link

My two favorites are recently:

• nnn for managing files
• miller for all my CSV needs
• rg for searching in files
• navi for my cheatsheet needs
• nb for my jotting needs
• ledger because I love to know about my money
