Using PSFTP.EXE to copy differential data from a remote SFTP site to a local UNC path.

I am trying to use psftp.exe to copy files from an external SFTP site to a local UNC path.  

The command I use is "psftp.exe server1.xyz.com -b task.txt -l username

In my task.txt file, I have the following:
      lcd "\\localserver\file path"
      cd remote_file_path
      mget "*.*"

Questions:
1. I am using -l to specify the username.  How do I specify the password?
2. When I use mget "*.*", I am copying all files from the remote sftp server to my local file server.  
Is there a way I can copy only the differential data to the local UNC path?

Please advise.

Many thanks.

There is no build-in mechanism for psftp to understand differential data, so the answer is no.

You can use the -pw option or key pairs. For instance -

Try -

psftp -pw 'password' username@server1.xyz.com -b task.txt 

Open in new window

If psftp is an option so is pscp

pscp username@remotehost:/path/to/file store_here
pscp -r username@remotehost:path/to/directory/* strore_here

using puttygen and pageant you can have public key authentication rather than password/interactive.

If you use ssh you can use rsync over ssh and that will do differential data.


rsync -avz -e "ssh" server1.xyz.com:/remote_file_path/  /local_file_path


There are lots of tutorials out there for doing this - here's one:
