How to check if a file exists

Question

So my problem is basically is that I can't figure out a condition to give an error message if can't find the file given as argument.

if ARGV.empty?
    puts "Give me a file!"
elseif [condition]
    puts "Can't find the file"
else
    file = File.open(ARGV[0])

What I exactly need is the condition for the elseif.

Ruby's `File.open` will throw an exception if it cannot find the file. Isn't that good enough? — David Grayson, Jun 11 '17 at 19:47
