Is it possible to transfer a file from a Linux Bash script to Windows without mounting the server folder?

Question

I am writing a script (Bash) to transfer files from my local Linux machine to Windows servers. The Windows servers are accessible normally using the SAMBA shares, and I am able to mount a folder to my Linux machine using the mount.cifs command with the proper Windows credentials.

Because I do not want to mount every server in advance nor mounting dynamically using sudo (the script is executed as a normal user, not root), I am just wondering if the server can be accessed by another means, like a TCP pipe or a similar way.

For example, under Windows I can mount my server's folder to a drive letter using the net use command, but as well without having being mounted like this:

c:> net use \\my-server.domain.com passwd123 /user:domain\myuser
c:> cp d:\myfiles.zip \\my-server.domain.com\d$\temp\destination

And if I make a net use, I can see the open connection (without letter assigned):

    Status       Local     Remote                    Network
-------------------------------------------------------------------------------
OK                     \\myserver.domain.net\IPC$
                                                Microsoft Windows Network
The command completed successfully.

I do not want to install sshd nor ftpd on the Windows Server. I am looking to do it only with the SMB protocol. As a fallback I will execute a mount like sudo mount.cifs [options] /mnt/temp-folder and sudo umount /tmp/temp-folder after the copy of the files.

You can use the smbclient program to give you an FTP-like interface to the Windows file share without having to install FTP on the Windows machine.

Here follows some examples:

Transfer file from local (unix/linux) to Windows:

smbclient //server.domain.org/d$ <password> -W domain.org -U <my-user> -c "put file-local.xml folder1\folder2\file.xml"

Transfer file from Windows to Linux:

There are two options, the first is using the command 'get' with smbclient and a the second, a shortest one: smbget:

1. smbclient: `smbclient //server.domain.org/d$ <password> -W domain.org -U <my-user> -c "get folder1\folder2\file.xml file-local.xml"`
2. smbget: `smbget -u <my-user> -p <password> -w domain.org -o destination-file.txt smb://server.domain.org/d$/folder1/folder2/source-file.txt`

You might try something like wput [options] [file]... [url]... ftp://[username[:password]@]hostname[:port][/[path/][file]] or wget
