Magento – Missing commands for Magento command line

In my case, it worked using sudo

sudo bin/magento setup:upgrade

EDIT 19/02/16

Actually, the "sudo" solution is more a workaround for bad permissions/ownership of Magento files.

If you don't already have a Magento file system owner, create one and add it to the apache group.

adduser magento
passwd magento
    //CentOS
    usermod -g apache magento

    //Ubuntu
    usermod -g www-data magento

//restart apache
    //CentOS
    service httpd restart

    //Ubuntu
    service apache2 restart

Now that you have your user, you can set the ownership and permissions (with root or an user with sudo)

cd /var/www/html/magento2beta/magento2
find . -type d -exec chmod 770 {} \; && sudo find . -type f -exec chmod 660 {} \; && sudo chmod +x bin/magento
//CentOS
chown -R magento:apache .
//Ubuntu
chown -R magento:www-data .

Switch to the magento user

su magento

Now you should be able to run php bin/magento setup:upgrade or any other command with your magento user

first run the cmd composer install in you folder then run this cmd

php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy (or) 
php bin/magento setup:static-content:deploy -f
php bin/magento indexer:reindex
php bin/magento cache:flush (or)
php bin/magento cache:clean

after setup:upgrade you remove the generation, page_cache, cache, view_preprocessed, static rm -rf var/generation/* var/cache/* var/report/* var/page_cache/* pub/static/* var/view_preprocessed/* `
