Tree

I wanted a quick way to generate an index.html for a directory of html files that grows by 1 or 2 files a week. I don't know any html (the files are exports from my tiddlywiki)...

tree is just the answer.

Say I have a file structure like this:






        
./html-files
├── file1.html
└── file2.html

To generate a barebones simple index.html we can use tree as follows:

tree ./html-files -H "." -L 1 -P "*.html"

and get the following:






        
<!DOCTYPE html>
<html>
<head>
 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 <meta name="Author" content="Made by 'tree'">
 <meta name="GENERATOR" content="$Version: $ tree v1.8.0 (c) 1996 - 2018 by Steve Baker, Thomas Moore, Francesc Rocher, Florian Sesser, Kyosuke Tokoro $">
 <title>Directory Tree</title>
 <style type="text/css">

which looks like this when you serve it up with python -m http.server
