Since it's using SSH, you should be able to do an SSH keyswap between the machines. You don't say what you're writing the script/program in, or on what version of linux, so it's hard to "kindly provide you a solution", but if it's PERL, check out the Net::SFTP module on CPAN.

I know we don't typically link to a different forum, but there's a nice scripting example snippet in the UNIX Shell programming scripting forum for using key based authentication in a sftp script.

Hi

Thanks for all your suggestions, i got the solution for SFTP non-interactive mode is as follows

#!/bin/sh

HOST=XX.XXXX.XXX
USER=yourusername
PASS=yourpassword

echo "Starting to sftp..."

lftp -u ${USER},${PASS} sftp://${HOST} <<EOF
cd somedir
get somefile
bye
EOF

echo "done"

Thanks

Thanks you so much for the previous script. You saved my day.

After hours of messing around with .netrc and creating batch files this script gave me the solution I was looking for.
Thanks!

You do realize two things about this thread, right? First is that it is getting near 15 years old. Second that FTP is the wrong solution for just about anything these days and the correct answer was the SFTP client using the -i and -b options or setting the equivalent in ~/.ssh/config. It's 2023, don't use FTP.
