a for loop based WP-CLI command to update all sites under document root at once

[ghost]

I suggest adding a new command that can be added anywhere in the system which updates all websites in a total way. As for now I do:

for dir in /var/www/html/*/; do cd "$dir" && wp plugin update --all && wp core update ; done

I don't have any problem but people who are very new to linux and just getting used to it might not feel comfortable working with such a long command so I offer 2 things:

• Making a WP-CLI shorter syntax command that does the same thing.
• Making sure the new "total update command" will also update themes.

For finding WordPress installs on the filesystem, you might want to check out https://github.com/wp-cli/find-command

Generally, I lean more towards helping users learn more about existing CLI tools, than replicating those tools in WP-CLI. See our "Shell friends" doc on this topic: https://make.wordpress.org/cli/handbook/shell-friends/

Do you have any suggestions on how we could improve our documentation, etc.?

I would add a note in the "commands" section regarding to automizing update of plugins and core, when a user has 2 or more sites. That's what I personally looked for in the command section at the time.

A regular bash alias would maybe be a good idea to make this easier.

Of course I can create a Bash alias, but new users not necessarily can create Bash aliases or understand the command above, hence, My point is that we should make this more accessible to new users via a WP-CLI command. This is something worth considering I think.

This could be done through great documentation I think instead.

Documentation is the best place for this. I've created a new issue for it: wp-cli/handbook#175
