execuate command problem

[Martin Sharon]

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.

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.

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