Sftp equivalent to ftp -n
Hi all.

I can put ftp command in shell script together with the password using
Code:
ftp -n 10.1.2.34 << EOF
user userid password
cd /test_dir/
prompt
bin
get filename.txt
EOF

But the -n option is not available for sftp.

What alternatives do I have then to bypass the password prompt?

Thank you.

Use ssh keys or an expect wrapper. You could also use lftp with the -u username,password option.

Not unless you have root privileges or build then from source.

As Corona688 mentioned using public/private key pairs will be the most secure, Can you give details of why it didn't work(i.e. errors) after you setup the key pairs on each host?

Example use:
Code:
sftp -b /dev/stdin -v -o BatchMode=yes -o IdentityFile=/export/home/user/.ssh/id_rsa -o Port=22 user@host <<ENDSFTP
cd /home/user/test
put /export/home/user/test/test.txt test.txt.xferring
rename test.txt.xferring test.txt
quit
ENDSFTP
rc=$?
if [[ $rc != 0 ]]    then
    print "Error occured...$rc" `date "+%Y-%m-%d-%H.%M.%S"`
else
 print "Successful transfer...$rc" `date "+%Y-%m-%d-%H.%M.%S"`
fi
