Share folders in Ubuntu server using through CLI...

Change the samba configuration file located at /etc/samba/smb.conf as follows...
i. For authentication-based-access, append...

[private]
     comment = Private Share
     path =  /tmp/pri-share
     browseable = no
     read only = no

ii. For anonymous-read-only access

[public]
      comment = Public Share
      path = /tmp/pub-share
      read only = no
      guest only = yes
      guest ok = yes

Be sure, while accessing the shares from either windows or linux box, you are using 'private' of 'public' as share names instead 'pri-share' and 'pub-share'.

e.g. \\192.168.1.10\private
smb://192.168.1.10/private


..............Done!!!
