sftp automated script

[Links Moodley]

What is the syntax in HP Ux script to invoke sftp using the open command? my script looks like this
open nashualocal
user FTPUser N@shua!
type ascii
cd Nashua/New_Orders
lcd /usr1/EMBRACE/EMBRACE.LIVE/NASHUA.SALES
mget *.csv
lcd /usr1/EMBRACE/EMBRACE.LIVE/NASHUA.SALES.BACKUP
mget *.csv
cd /Nashua/New_Orders
pwd
!uuencode /usr/bin/nash1.log nash1.log.csv | mailx -m -s "Nashua Confirmation" l
moodley@tarsus.co.za hdebloe@tarsus.co.za ebrown@tarsus.co.za
quit

Hi:

Setup public ssh keys between your servers. Then you can do something like:

# cat .mysftp
HOST=$1
FILE=$2
sftp -b - <lcd /tmp
cd /tmp
put -P ${FILE} ${FILE}.backup
EOF
RC=$?
print -u2 "\nSFTP returned ${RC}"
exit ${RC}

Regards!

Hi (again):

You can and should avoid passwords in scripts if you are automating Secure Shell functions like 'scp', 'sftp', etc. Public keys provide the methodology.

Matti Kurkela gives a quick-step view here:

...and Doug O'Leary provides a detailed guide here:

http://www.olearycomputers.com/ll/ssh_guide.html

The 'known_hosts' file contains the public host keys for all known hosts. The per-user version is maintained automatically. Thus, whenever you connect from an unknown host, its key is added to the per-user file if you choose to acknowledge the fingerprint. If you don't, the connection can still be made, but you will be prompted the next time as if you had never connected.

The manpages for 'sshd' and 'ssh' offer more information.

Regards!
