I hope everything in that string is trusted and/or well-escaped. It
looks like popen doesn't have a way to take an array ala exec/system,
so you're stuck worrying about "';rm -rf" and other fun stuff (
like fi|lenames with fun(ny) characters).
puts IO.popen("echo foo | sed s/o/e/g").read
Is there a well-done open3 or other library for ruby? In perl, I always
use IPC::Run for any non-trivial system/pipe/subprocess stuff.
And I really have to ask why you need to fork a perl one-liner in your
ruby :-) If ruby's C API is so sweet and it has threads, just embed a
perl interpreter in a thread.
