Execuate command problem

ruby-talk
1

I want to execute a shell command in ruby, like this:

line = "tokyo paris london"
par = "23 23 11 43"
execute = "./comp #{line} #{par}"
puts execute

but the command executed is

./comp tokyo paris london
23 23 11 43

There is an "enter" there, how can I execute:

./comp tokyo paris london 23 23 11 43

without line changing?

thanks!

Works for me

17:03:46 bin$ ruby <<XX

line = "tokyo paris london"
par = "23 23 11 43"
execute = "./comp #{line} #{par}"
puts execute
XX

./comp tokyo paris london 23 23 11 43
17:12:42 bin$

You must have been doing something differently than posted.

Kind regards

Oh, I think the only difference is in my program

f=File.open(ARGV[0], 'r')
line= f.gets

line = f.gets.chomp to remove carriage return.
