How Do I Map a Drive Network Share Using the Linux Terminal?

You need to install:

sudo apt-get install smbfs -y

then Create a directory on your machine to use as a mount point for the share:
sudo mkdir /media/yoursharename
exp. sudo mkdir /media/nas

then I use the mount command to map a windows share folder
from your NAS server to the mount point you just created:

sudo mount -t cifs -o username=nasserverlogin 
//server/sharename /media/yoursharename

or 

sudo mount.cifs -o username=nasserverlogin 
//server/sharename /media/yoursharename

You should now be to access the share from your /media/yoursharename mount point.
