SFTP through KSH
Hi all, I am unable to sftp some files. I see on the internet there are no proper solutions given.

I use couple of different ways.

1) Script1.sh

#!bin/ksh

sftp -v user@server_name <<"ENDOFHERE"
mput test_sftp.txt
bye
ENDOFHERE




It prompts me for password and after i enter it will transfer the files.



But I need to automate with out manaul entering the password. can some one please give their insights to automate this.


I also tried this


1)Script1.sh

#!/bin/ksh

sftp -v -b param_file_test user@server_name


"param_file_test"

pwd
mput test_sftp.txt
quit

Thanks in advance

You need to use ssh keys.
Try your man page for ssh-keygen.
