I know this has been done before but search yields nothing :-
Just wondering how you can pipe output to ruby -e? I tried this but
it doesnt work :-(

#### borked
echo "hello" |ruby -e 'puts ARGV.to_s'



Thanks for any help you may be able to offer.

A couple possibilities:

echo hello | ruby -e "puts gets"
echo hello | ruby -e "puts ARGF.read"

ruby -e 'puts ARGV.to_s' `echo hello`


Hope this helps,

echo "hello" | xargs ruby -e 'puts ARGV.to_s'

will also work.
