Subprocess's stdout and stderr aren't redirected to the notebook

[mrkn]

When I execute system("echo Hello World"), the output of echo command wasn't displayed on the notebook, but was appeared on the console.

Just tested this on a iruby fresh install:

ProductName: Mac OS X ProductVersion: 10.14.6 BuildVersion: 18G2022

IRuby 0.4.0, Ruby 2.6.3 Jupyter console 6.1.0

In [1]: system("echo Hello World")
Hello World
Out[1]: true

If this is still relevant, could you please provide which version of iruby are you running and its dependencies versions? Thanks in advance.

Edit: nevermind. Just reproduced it. I'm going to investigate this further.
