Creates client for samba server

The script must be run as a root.




Usage:

$(basename $0) <server-address> <share-name> <mount-place> 
               [--user <user>] [--noauto] [--password-credentials <username>;<password>] [--nomount] 
               [--help] [--debug] [--log log]

where

 device-address           - Address of the server (e.g. IP address)
 share-name               - Share name, as published by the server
 mount-place              - Place where the share will be mounted. The directory will be created, if not existing
 --user <user>            - What user shall be the owner of the share?
 --password-credentials   - File that lists password credentials in the format <username>;<password>,
                            e.g. adam;szakal
 --noauto                 - If set, the mount will not be mounted during boot time
 --nomount                - If set, the mount will not be mounted now
 --debug                  - Flag that sets debugging mode. 
 --log                    - Path to the log file that will log all meaningful commands


Example:

$(basename $0) 192.168.10.2 other /media/adam-minipc/other --password-credentials adam;szakal
