Warning: Input is not from a terminal

This morning I was using locate to find some configuration files, and I wanted to edit them directly in Vim.

locate config.xml | xargs vim -R

Vim starts but gives this warning:

Warning: Input is not from a terminal

When you exit Vim, you’ll find your terminal is probably borked. You can use reset.

Looking for the cause of the problem, I found this:

https://superuser.com/questions/336016/invoking-vi-through-find-xargs-breaks-my-terminal-why/336020#336020

And following a few more links found the solution

locate config.xml | xargs -o vim -R

From xargs man page:

-o, --open-tty
    Reopen stdin as /dev/tty in the child process  before  executing
    the  command.  This is useful if you want xargs to run an inter‐
    active application.
