I put the above content in a file and doing

Code:

I am using expect function for doing this.. below is the script i am using.
Code:
#!/usr/bin/expect
spawn sftp <userid>@<ftpServerName>
expect "password:"
send "<password>\n";
expect "sftp>"
send "cd /home/xyz\n"
expect "sftp>"
send "lcd /ftp_data/xyz\n"
send "mget *\n"
expect "sftp>"
send "exit \n"
interact

expect function included in tcl package or you can download it from any open source website.

Using expect to kludge passwords into ssl is a really bad idea. It is intentionally difficult to put passwords automatically into ssl. If you want it to be automatic, use shared keys.
