Mounting VirtualBox shared folders on Ubuntu Server 16.04 LTS

This guide will walk you through steps on how to setup a VirtualBox shared folder inside your Ubuntu Server guest. Tested on Ubuntu Server 16.04.3 LTS (Xenial Xerus)

Steps:

Open VirtualBox
Right-click your VM, then click Settings
Go to Shared Folders section

Find out what package installed the config file:

$ dpkg -S unity-greeter.conf
unity-greeter: /etc/lightdm/unity-greeter.conf

As you can see, the name of the package is unity-greeter.

If you deleted a directory, like /etc/pam.d, you can list every package that added to it by using the directory path:

You can have finer control with:

rake db:drop:all

And then create the database without running the migrations:

rake db:create:all

Then run all your migrations:

	# username
	# appname
	# gemset

	[Unit]
	Description=Puma HTTP Server
	After=network.target

	[Service]
	Type=forking

	### Add trailing slash if needed

	STR="/i/am/a/path"

	length=${#STR}
	last_char=${STR:length-1:1}

	[[ $last_char != "/" ]] && STR="$STR/"; :

	echo "$STR" # => /i/am/a/path/
