From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

correct way to echo | sudo tee (lemmy.world)

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.

Are you saying it waits forever, or you read somewhere it will wait forever and you want clarification?

Guessing that file doesn't exist already is the problem, and you don't even need to use tee in this example.

what I was saying was that echo "text" | sudo tee newfile would hang and never return and needs to be interrupted. I just noticed this does not happen in bash but I was testing in zsh.

you've missed the point here I'm afraid. But I'll blame it on my for not explaining properly what I was intending to do.

ZSH is bash-compliant, but will not always behave like bash in all situations.

Add sh -c before echo and see if that works

yep. that did it. I had to wrap the entire thing in quotes though

sh -c "echo 'test' | sudo tee newfile"
