How to capture stderr while using backtick?

Easiest way - don’t use backticks. Use Open3.

e.g.

require “open3”
in, out, err = Open3.popen3(“system command”)

I am using backticks in my ruby script to run DOS
commands, but cannot figure out how to separate the
stdin from stderr.

Note that Shashank uses mswin32 version, and open3 needs fork.

Open3 is one of pending list under Windows.

Tried that but: fork in popen is not implemented on mswin.
Sorry!
