    As the title says, how can I download a file using scp over two hops? Preferably, the files must not be stored (written to disk) at any point in the first server, just transfered through.

    Using simply : 

    scp user1@host1:/location/of/file user2@host2:/location/of/destination

    If you have a traffic forwarder (netcat, socat, etc.):

    scp -o ProxyCommand="ssh FIRST_HOP socat tcp:SECOND_HOP:22 stdio" \
        FIRST_HOP:/path/on/second_hop/file local/path/

    I have connected to a Unix server using SSH from my terminal from my Windows client.

    How do I copy files from the Unix server to the Windows client? Can I use the scp and rcp commands? Or are there other ways to do so?

    scp is the way that we do this. If you're using something like putty, it comes with pscp as part of it.

    I prefer pscp over the standard scp since it allows you to specify a password on the command line, something useful for scripting.

    An example invocation from one of my scripts (details changed to protect the innocent):

    pscp -pw paxpwd src.tar.gz [email protected]:/usr/pax/tmp/src.tar.gz

    This copies the src.tar.gz file from my local (Windows) directory to /usr/pax/tmp on my pax.com UNIX machine, using the pax/paxpwd user and password.

    Your particular use case would be satisfied by:

    pscp -pw biranchipwd [email protected]:abc/xyz.txt xyz.txt

    Keep in mind that placing passwords into scripts is not generally a good idea since it means anyone that breaks into your local machine can easily break into the other machine as well.

    you should check SFTP. Filezilla is able to handle SFTP session. also putty provide a pscp command.

    You can use scp directly on the command prompt itself: For example:

    c:>scp [email protected]:/home/myuser/test.properties .

    [email protected]'s password:
