Why ? I often swtich between PHP versions 5 and 7 and sometimes running composer update command messed things by incorrectly updating versions of some of the dependencies based on current PHP version I am working with.

Install

You can install it globally by typing:

composer global require sarfraznawaz2005/composer-confirm

That's it. Now on any project when you type composer update or composer install, you will be asked if you want to proceed.

To remove it:

composer global remove sarfraznawaz2005/composer-confirm

FYI, you can skip any plugin when installing/updating by appending --no-plugins argument, example:

composer update --no-plugins

Thanks
