Edit the Samba Config, smb.conf
(Location is /etc/samba/smb.conf)
Move the smb file to a backed up state so you can fall back to orig config.
sudo mv /etc/samba/smb.conf /etc/samba/smb.conf/$(date +%F)

ls /etc/samba/smb.conf.2019-XX-XX

sudo bash
grep -ve ^# -ve ‘^;’ -ve ^$ smb.conf.2103-11-26   >  smb.conf
Understanding the GREP Filter
The command may look a little messy but is really useful to us.

-ve ^# : First we remove lines that start with a #
-ve ‘^;’ : The we do the same for lines beginning with ; Note the quotes here as the ; has other meanings so we escape the semi-colon in the quotes
-ve ^$ : Finally we remove empty lines
> : This is used to redirect the output to the new smb.conf.
We go from and incredible 333 lines in the original file to a minute 34 lines in the new file. This way, the result is quick and we have not lost out documentation as it is in the backup.

Adding a share definition
edit /etc/samba/smb.conf and add /data directory
[data]
  comment = Data share
  path = /data
  browseable = yes
  read only = no

use "testparm" ?

Restart Samba service
Service samba restart

Creating samba users
smbpasswd -a root
smbpasswd -a pi
