SMB Client Commands Through Shell Script

Question

I have a shell script, which I am using to access the SMB Client:

#!/bin/bash
cd /home/username
smbclient //link/to/server$ password -W domain -U username
recurse
prompt
mput baclupfiles
exit

Right now, the script runs, accesses the server, and then asks for a manual input of the commands.

Can someone show me how to get the commands recurse, prompt, mput baclupfiles and exit commands to be run by the shell script please?

Answer 1

I worked out a solution to this, and sharing for future references.

#!/bin/bash
cd /home/username
smbclient //link/to/server$ password -W domain -U username << SMBCLIENTCOMMANDS
recurse
prompt
mput backupfiles
exit
SMBCLIENTCOMMANDS

This will enter the commands between the two SMBCLIENTCOMMANDS statements into the smb terminal.

Answer 2

smbclient accepts the -c flag for this purpose.

 -c|--command command string
       command string is a semicolon-separated list of commands to be executed instead of
       prompting from stdin.
       -N is implied by -c.

       This is particularly useful in scripts and for printing stdin to the server, e.g.
       -c 'print -'.

For instance, you might run

$ smbclient -N \\\\Remote\\archive -c 'put /results/test-20170504.xz test-20170504.xz'

smbclient disconnects when it is finished executing the commands.
