Replace FTP with SFTP

Hi All,

I am in the process of replacing SFTP instead of FTP to make data more secure. In one of my FTP script I have Quote Site command. I would like to know, what is the option to replace this in SFTP

Code:
ftp -n -v <<! | tee -a $LOG | grep "Transfer complete" >/dev/null
   open $remote_address
   user ${remote_login_id} ${remote_password}
   quote site $quote_site_cmd
   cd $remote_dir
   binary
   put $local_file $remote_file
   quit

Please help me to solve this.

Thanks in advance
Vishnu

sftp is not a drop-in replacement for ftp. 'get' and 'put' work mostly the same, but passwords and such are very different. It doesn't do translation like FTP does, it transfers everything binary.

Code:
sftp ${remote_login_id}@${remote_address} <<EOF
cd ${remote_dir}
put ${local_file} ${remote_file}
quit
EOF

It will not take passwords from anywhere but the terminal, you cannot put them in the here-document. This is a security precaution, since stored plaintext passwords are extremely difficult to keep safe.

If you want it to login automatically, you should arrange safe, secure passwordless logins via keys instead.

Without knowing what $quote_site_cmd actually is, I cannot say what you should replace it with. It's possible there is no drop-in replacement -- sftp doesn't do a lot of the odd inter-mainframe translation things ftp used to. On the other hand, these things are generally unnecessary now. (But may be relevant if dealing with old mainframes.)
