If you are newish to Linux (like me) from Windows, then some of the simple things which come quite naturally to you on Windows is a little embarrassing and challenging.
For example, I got a new WHS and wanted to mount the music drive and wanted to create a new host file entry to point to the new WHS. Now on Windows this is quite simple and can be found in
YOUR-OS-DRIVE\Windows\system32\drivers\etc\hosts. But on Linux you will find this in
\etc\hosts. If you want to edit it you will need to type something like this a shell:
sudo gedit /etc/hosts
sudo is required as you need admin privileges to modify the file.
gedit is the graphical editor; you can replace that with another editor of your choice.
