````### Programming questions
````shell script
$ howdoi js hex to int
hexString = yourNumber.toString(16);
yourNumber = parseInt(hexString, 16);
Source: https://stackoverflow.com/questions/57803/how-to-convert-decimal-to-hexadecimal-in-javascript
````## Usage
howdoi [-n -v -h -i] -- question-n Number of results (default is 1)
-v Show full answer (otherwise shows only code)
-i Interactive or REPL mode (useful for hotkey binding)
-h Shows this help## Installation
Just run the following commands (requires PHP 5+).
````shell script
$ 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.![popup](./popup.gif)
(you can ask questions in a popup too by pressing a hotkey - as described below)
### Setup hotkey binding
- Copy [popup.sh](./popup.sh) in your `~/bin` folder (or the folder in which you've downloaded *howdoi* script)
- Run `chmod +x ~/bin/popup.sh`
- Go to *Settings > Keyboard > Shortcuts* and add a new shortcut to `~/bin/popup.sh`
- 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!## Feedback

## Caveats- 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).## Licence
