Ruby: execute bash command, capture output AND dump to screen at the same time

So my problem is that I need to have the output of running the command dumped to the screen and also capture it in a variable in a ruby script. I know that I can do the second part like this:

some_variable = `./some_kickbutt`

But my problem is that I need it to still print to the console as Hudson captures that output and records it for posterity's sake.

thanks in advance for any ideas...

Just tee the stdout stream to stderr like so:

ruby -e 'var = `ls | tee /dev/stderr`; puts "\nFROM RUBY\n\n"; puts var' | nl

ruby -e 'var = `ls | tee /dev/stderr`; puts "\nFROM RUBY\n\n"; puts var' 2>&1 | nl
