A CLI Command That Only Updates Neovim Plugins

I only just learned the command that updates plugins in a Neovim (Vim) setup that uses vim-plug.

Until now I opened nvim, opened the : command window, and typed :PlugUpdate.
That is fine for a single machine, but repeating the same steps on several hosts is tedious.
It turns out you can run it from the command line as well.

$ nvim +PlugUpdate +qall

With this, you can drop it into a script or an Ansible playbook.
