html - Sinatra executing ls on sever side -


i trying show in chrome using sinatra, result of ls. explorer gets in "connecting..." loop.

my code is:

require 'rubygems' if ruby_version < "1.9" require 'sinatra/base'  #this webservice launch gamma project #using request @ principal webpage class myapp < sinatra::base   '/'     result = exec "ls"     puts result    end    end

i not sure of puts, think maybe not apropiate method. happening , how can solve it?

ps: in explorer used localhost.com:4567/

use backticks ( ` ) instead of kernel#exec command. former returns string can use in ruby process. latter throws execution context new process , has no return value.

get '/'   result = %x`ls`   puts result end

note call puts not nice , you'll want format or parse/manipulate further. @ least you'll can use.
