REST Command Equivalent for SFTP (SSH-FTP)

Hi,

I have 2 doubts regarding FTP and SFTP.

1. I need to download only a certain part of a file located on an ftp source.. i.e. about the last 200 bytes. I was able to use the "REST <location>" to start download from <location> point to the end of the file. But, SSH-FTP or SFTP does not support the REST command. Is there an alternative to REST in SFTP? My basic task is to download a file from an offset of my choice.

2. I need only a limited amount of data from the file, i.e. about 50 bytes from the 200th byte of the file. I could start download from 200th byte using REST, but, am unable to find a mechanism by which I can download only the necessary content by specifying its size.

Thanks in advance.

Hey,

Can somebody help me out.. This is real urgent and has been delaying my work for long.

Waiting for some response in anticipation.

check out cUrl and its range option. http://curl.haxx.se/docs/manpage.html

Thank you DonR. I've already seen that.. but I need to connect and download from the ftp using my JAVA code, and it needs to be cross platform. Do you know of any command sequence or procedure to implement using some java compatible library?

sorry, but, I know nothing about JAVA
