UNIX and Linux Applications

Hi
we need to implement SFTP through unix shell scripts. I have seen many posts, in which there is discussion about non-interactive,automated SFTP.
Can anyone please send me the sample code for SFTP shell script. We are using SFTP to transfer the files from the host server to the target server.

There are plenty of possibilities, you can create quite large matrix with options, let us know more about your specs : OS, users ( got root ?), language, uploads, downloads. Actually, if you have clear requirements and little bit more patience to search in the forum, you will find many different solutions.

We are looking to run an SFTP Shell Script, from a server A(Database Server), to be able to transfer files from a server B(Application) to the Destination Server C.

Basically we need to SFTP a file from one server to another, with the script running on a third server.

Any assistance with this would be great.Sample codes would be of great help.

Thanks

All servers are UNIX based.

I see, well, in my opinion TCL/expect based code will be a good choice. Sample code :

Code:

#!/usr/bin/expect

set timeout -1

spawn sftp -oPort=22 $user@$host
expect *assword:
send "$pass\r"
expect sftp>
send "put file1 newFileName\r"
expect sftp>
send "exit\r"
expect eof

The above will connect to a host, and will transfer a file via SFTP. Modify per your needs. Note - you can also use autoexpect, which will record your actions and will generate the script.

I am attempting to do the same with a script. The Sun Sparc9 Server I maintain does not have the expect command located on the hard drive. Is there another command that works the same?
This is a govt. Server, so downloading files to it is not an option.

wsiefkas,

You can use ssh's pki (keys) to facilitate interaction from a shell script. Simply look at the man pages for : ssh-add, ssh, ssh-agent, ssh-keygen, sshd, etc.. for details. This does
add to administrative overhead (key-management and key maintenance) in a way that an expect based solution avoids.
