Can someone explain why this would make the command wait forever? What is tee waiting for?

echo "test" | sudo tee newfile

What would be a scriptable workaround for such cases?

Edit: this command would not terminate in zsh. This works fine in bash tho.

    I just switched over to bash and it worked lol. It just didn’t return for me in zsh…

      I use zsh and it works fine for me fwiw. Same with zsh --no-rcs (which doesn’t load zshrc). Maybe you have some weird setting enabled?

      My initial guess was that sudo would eat up the echo’d foo as the password. Maybe sudo works differently when invoked via zsh?

        sudo does not prompt for password in my container. It just elevates the privileges straight away. Yeah, it’s hard to tell. Or test for that matter.

        no way. I’m in /tmp for this one

        echo 'test' | tee newfile
tee: newfile: Permission denied
test
echo 'test' | sudo tee newfile #the prompt never returns when running this in zsh
