Hi, as I've mentioned in another article, because of my job as a web developer, I have very little time for posts and videos.

It goes without saying that when I get time I will upload all of my archive I have created from time to time to troubleshoot problems that every company faces in its day to day life, from almost free cloud setup to multiple e-shop automations and more, as well as computerization.

Today, I am giving you my personal Ubuntu Server master command file that I had made for Ubuntu Server in Google Cloud (I will be uploading videos for $ 300 free Virtual Private Server to Google Cloud and how to claim it, setup, settings etc)

Note that some commands may not have the sudo up front, so add it or get admin rights with sudo su - on the console to prevent it from being used.

23. File rights: sudo chown -R username:group directory (will change ownership (both user and group) of all files and directories inside of directory and directory itself.)
    sudo chown username:group directory (will only change the permission of the folder directory but will leave the files and folders inside the directory alone.)
    view all users: compgen -u
    view all groups: compgen -g
24. Rights chmod: all directories inside a folder to 755: drwxr-xr-x
    4 is read
    5 is read/execute (execute is always needed for directories)
    6 is read/write
    7 is read, write, and execute
    The first number is Owner, the second is Group, and the third is Other. Thus 644 is 
    sudo chown -R www-data:www-data wp-content/uploads/
25. Connect as root: sudo su -
