sudo tee, as present in an original book, will cause weird behaviour of SSH client, because binary data will present on stdout, which can cause crash SSH. I think smart people will use 'su', or 'sudo su' ('sudo -i') without additional 'sudo'.

Can you reproduce a crash? Generally speaking we want the instructions to work as is, without the user (which might be inexperienced) having to change the command.

You need to run it as a non-root user.

You need to run it as a non-root user.

That's a default behaviour an 'tee' utility, doesn't make sense, am i root or not.
