Instead of entering each command individually is there a single commande that I can enter to deploy content and to also clear the appropriate folders?
you could add a alias to your command line like so
alias deployit='php bin/magento setup:static-content:deploy && php bin/magento cache:flush && rm -rf var/generation'
or you can seperate them
alias deployit='php bin/magento setup:static-content:deploy' alias cacheit='php bin/magento cache:flush' alias genit='rm -rf var/generation'
its up to you how you do it but the above should make it simple for you to run the commands simply type in the alias
