Why I use the D programming language for scripting (2021)(opensource.com)

    tr -s ' ' '\n' < file.txt

    awk 'NR <= 10 {print} {total += $1} END {print "total:", total}' monies.txt

    perl -Mojo -E 'a("/")->to_text(sub {
        "Hello World " . shift->req->url->path
    })->start' -l http://localhost:8080

    from flask import Flask, request
    
    app = Flask(__name__)
    
    @app.route('/')
    def hello_world():
        path = request.path
        return f'Hello World {path}'
    
    if __name__ == '__main__':
        app.run(host='localhost', port=8080)

    ruby -rwebrick -e"WEBrick::HTTPServer.new(Port: 8000){ |req, res| res.content_type = 'text/plain'; res.body = 'Hello World ' + req.path; }.start"
