Hi Chuong,

I’ve used ‘open3’

with succes.
(used open3 because I needed stdout and stderr)

Subject: [Rails] Execute shell command from Rails

Hi all,

Can anyone tell what is the way to execute OS shell command from
within Rails programs? I tried to use “exec” but it terminate the
console (which run “ruby script/server” originally).

Thank you very much.
