Hi,
thanks for reading the book!
I was just about to answer when I recognized that I was about to restate the
text that follows the example:
We’re using the pipeTo method of Process, which is invoked by using the
overridden
or (|) operator. Then we wait for the process to finish with a safe time to
wait, and
print the result.
The observant reader (yes, that’s all of you!) will have recognized that
although
the code is a slick solution, there’s also a pure Groovy solution that’s
platform independent
In other words, this solution _is_ platform dependent and cygwin is a bit of a
"unusual" platform to run commands at...
keep groovin'
