You can use the utility "expect".

Download it from the HP Porting Centre

Seems to me you're better of using ssh or remsh. That way you can configure it to connect to the other side without ever sending a password over the network.

ITRC Knowledge Base document KBRC00001309 shows how to execute ftp in a shell script.

I'm with Elmar on this one.

"remsh hostname command" is the simplest form assuming there is a .rhosts file on the host you are connecting to in the home directory of the user you are connecting to that has the source hostname in it.

remsh is less secure than ssh and shouldn't be used where the network is untrusted. "ssh" on the other had, is more secure but a bit more difficult to get it to not require a password (at least it is for me because I've never done it).

Hi Hari,

As Chris Said already Use "Expect" (It is a small scripting language like shell and it is available for almost all unix falvors).

Expect script is used to automate interactive command based utilities like, telnet , ftp, rlogin etc.

It can be embedded with Shell script too.

As others have said - you can use expect or rsh.

If it's just ftp, you can do it with .netrc file.

For the user that executes your ftp script, create a .netrc file in the home dir with the permissions 400, owner them:sys

In the file you put:

machine ip.of.remote.machine login loginid password thepassword

Then in your script, remove the
user < pass word>
line.
