예상대로 작동하지 않는 Ruby 스크립트의 stderr 리디렉션

출력 중이라고 생각되는 명령이 있습니다. 해당 명령으로 stderr리디렉션해도 여전히 출력이 화면에 인쇄되기 때문입니다.stdout/dev/null

stderr그러나 으로 리디렉션하면 /dev/null화면에 출력도 인쇄됩니다.

또한 모든 출력을 then으로 리디렉션하면 /dev/null예상대로 작동합니다.

어떻게 그래? 1>적어도 2>좀 잡아야 할까요 &>?

아래는 예입니다:

$ HOME=/tmp/fakehome/ bundle exec bin/fullstop https://github.com/mbigras/fake-dotfiles
stderr output of 'git clone https://github.com/mbigras/fake-dotfiles': fatal: destination path 'fake-dotfiles' already exists and is not an empty directory.
Error running 'git clone https://github.com/mbigras/fake-dotfiles'
checkout dir already exists, use --force to overwrite
$ HOME=/tmp/fakehome/ bundle exec bin/fullstop https://github.com/mbigras/fake-dotfiles 1>/dev/null
stderr output of 'git clone https://github.com/mbigras/fake-dotfiles': fatal: destination path 'fake-dotfiles' already exists and is not an empty directory.
