newbie: functions don't work in script

Christoph Klocker

sorry for this newbie question, just started ruby programming today,

Try to work me through the book Programming Ruby

the script:

#!/usr/local/bin/ruby
a = [ "a", "b", "c" ]
a.include?("b")

returns me nothing,
if I do the same in "irb"
it returns "true"

why does it not work in the shell script??

Try changing the last line of your script to,
puts a.include?("b")
irb automatically prints out the evaluation of an expression.

Christoph,

your script doesn't do anything with the return-value of 'include?'

try this:

#!/usr/local/bin/ruby
a = [ "a", "b", "c" ]
p a.include?("b")
