I have a file in my remote server which needs to be transferred to sftp box.
I do have the password, port and username for sftp box.
Please share me a shell script programming to understand how this can be done.
you can go for passwordless authentication between remote server and sftp box via sharing the public key .
OR , you can use
scp filename sftpuser#sftphost:/$destination_Path

Is it possible to read an image in a remote server with ssh in a matlab code?
I mean, I want to do this, but Matlab is not allowing:
image_file=strcat('sftp://user#ssh_server/user/images/image_name.tif');
imread(image_file);
I can login in this ssh server without password.
Assuming that you are on linux/unix, you can use scp from matlab to fetch the file, e.g.
!scp username#localhost:/tmp/source/test.png /tmp/
% please note ! at the beginning.
This will prompt you for password offcourse. Thus, if you want, you can setup public-key authentication for passwordless scp command.
I am very new in shell scripting , i want to download some files from linux remote server ,so how can i proceed for that.That remote server is ssh based .
first of all, ftp service is better choice to get files from remote server.
If only sshd service is available, then you may use ssh based command sftp or scp.
However, using sftp or scp commands will invoke an interactive password prompt, which is a problem in shell script --> You have to ask for help to expect command. see Automate scp file transfer using a shell script .
Besides expect, you may also set up trust relationship between two servers, then you may use scp without password. See http://www.linuxproblem.org/art_9.html

How to do the sftp without the password prompt?
If I like to download aaa.txt file at /remote/mike/files to my local directory /local/mike/downloaded, how to build a script to do all of these work?
Since sftp runs over SSH, you can place your public key on the remote server.
If for some reason you can't place your key on the server, then you can write an Expect script to send your password when the prompt appears. See this example.
