Here are my most used commands in Linux. Current favoured distibution is Ubuntu Server 16.04.3 LTS (Xenial Xerus).

# apt-get is the lower level, apt is meant to be more pleasant!

apt-get update    # updates the package lists
apt-get upgrade   # upgrades current packages
apt-get dist-upgrade  # distribution updates 

apt-get install openssh-server  # so can ssh, and scp into the machine

scp * dave@xps:wordpress/.
scp docker-compose.yml uploads.ini wp-config.php dave@xps:wordpress/.

chmod -777 *
