Just run the following commands (requires PHP 5+).
$ mkdir -p ~/bin && wget https://raw.githubusercontent.com/san-kumar/howdoi/master/howdoi -O ~/bin/howdoi && chmod +x ~/bin/howdoi $ sudo ln -s ~/bin/howdoi /usr/local/bin/howdoi $ howdoi check my linux version
Interactive or Popup mode
It is possible to run this outside the terminal interactively via a hotkey binding. It can also handle simple programming related questions too.
(you can ask questions in a popup too by pressing a hotkey - as described below)
Setup hotkey binding
- Copy popup.sh in your
~/binfolder (or the folder in which you've downloaded howdoi script)
chmod +x ~/bin/popup.sh
- Go to Settings > Keyboard > Shortcuts and add a new shortcut to
- Assign a hotkey (e.g. Ctrl+Shift+H) to your new shortcut.
- Now press the hotkey and you should see a popup where you can type your question!

Thank you everyone who encouraged me and voted for this project on Hacker news. Seeing comments like these really makes the work I've put into it worth it and now I want to make more such projects!
- It's just a quick hack to save you a few clicks. I wrote this in just a few hours, so it's not perfect.
- Right now, it prefers Ubuntu solutions over other linux distros.
- Just to clarify this only prints the answer, it does not run any code on your machine (in case the screenshot gives you the wrong impression).
