You can easily join elements of an Array together with `join`. ARGV is an Array.
ARGV.join(" ")
Problem
Question: Is there a simple way to print out an array in Ruby with elements separated by spaces? Details: I want to use Ruby to Benchmark commands and run the command. Something like: ``` script.rb ./command_name arg1 arg2 arg3 ... ``` For example: ``` script.rb ls -lh ``` should run `ls -lh`. I tried to do this with: ``` require 'benchmark' puts Benchmark.measure{system(ARGV.to_s)} ``` (note ignore benchmark for this question I just included that because that what I'm using this for) but that does not work because ARGV gets printed without spaces. For example `ls -lh` becomes `ls-lh`. Obviously I could create my own string by parsing the ARGV array and inserting spaces between elements in loop. But I assume there is a more elegant Ruby solution but I haven't been able to figure one out yet so I'm wondering if anyone has suggestions.
