Backtick commands and stderr

ruby-talk
1

When executing a system op using the backtick method, the standard
output is caught and returned in the assigned variable:

output= `ls -Al`

I am wondering what happens with the standard error output?

I believe you want to look at open3 or open4

... found something here:
http://www.ruby-doc.org/stdlib/libdoc/open3/rdoc/index.html, but it
doesn't look like working on Windows.
