Join Scott Simpson for an in-depth discussion in this video Navigating the file system and working with files, part of Up and Running with Fedora Linux.
- Some of the most basic and most often used commands…deal with folders and files.…I already showed you ls, which lists files,…but let's revisit it briefly.…The ls command with the -l option…lists files in the long format.…That is, it shows you some of the metadata…about files as well as just the name.…Starting on the left here is a column that starts with a d…if the entry's a directory, a dash if it's a file,…and an l if it's a link.…After that are nine characters that represent…permissions on the file.…
This set of characters is divided up…into three groups of three with the letters r, w, and x…either appearing or absent depending…on what the permissions are.…The first group of three…represents the file owner's permissions.…The second group represents the permissions…that users in the file's group have.…The last three represent the permissions…that everyone else outside the owner…or the file's group have.…R, w, and x stand for read, write, and execute.…For more on permissions,…I recommend that you take a look at…

Q: Why don't the VirtualBox Guest Additions install properly on Fedora 23?
A: It seems that the VirtualBox Guest Additions don’t like the version of the X.Org Server software that comes with the Fedora 23 ISO. Before installing the additions, make sure to run:
sudo dnf update
This will get the latest version of X.Org Server (currently 1.18). After that, restart the VM. Then run:
sudo dnf install gcc kernel-devel-$(uname -r)
This command installs the gcc compiler and updated kernel headers, which the Guest Additions need in order to build themselves. $(uname -r) takes the output of the uname -r command, which returns the current kernel version number, and uses it to request to install the correct version for your system. Then try installing the Guest Additions again. You should see "Installing X.Org Server 1.18 modules [ OK ].” Restart the system again, and the full-screen feature should work.
