Ruby - Find a file by name in a folder

Question

The situation is that there is a folder with some files (eg "1", "2", "3") and I need to request information about this file. One of the options is File.exists?, but it only searches by a strictly defined file name. In turn, I need to search for the required file by query from the input field, ie the name of the file is a variable that the user sets. Can you please tell me the best way to search for a file in a folder in this case?

Answer 1

I think what you want is something like this:

#!/bin/ruby

puts "What file are you looking for?"
filename = gets.chomp 

if File.exists? filename
  puts "File found! :)" 
  # do something else
else
  puts "File not found! :("
  # maybe do something else
end

It will take the user input and then determine if it the file exists with that name (exact match only).
