[CentOS] echo password into bash script

Hey guys,

 I'm trying to echo my password into some commands inside of a bash script.
But I think I'm going about it incorrectly.

Here's the top part of my script:

#!/bin/bash
pub="~/.ssh/id_rsa.pub"
dps_pass="my_pass"
ssh="/usr/bin/ssh"
scp="/usr/bin/scp"
for i in 10.10.10.2{5,6}
do
echo "xfring key up"
echo $dps_pass |  $scp $PUB  digitalplatform@$i:


And here's how it executes:

 #bash -x deploy_key.sh
+ pub='~/.ssh/id_rsa.pub'
+ dps_pass='nbcuV01P!'
+ ssh=/usr/bin/ssh
+ scp=/usr/bin/scp
+ for i in 10.10.10.2{5.6}
+ echo 'xfring key up'
xfring key up
+ echo 'my_pass'
+ /usr/bin/scp /Users/my_user/.ssh/id_rsa.pub digitalplatform at 10.10.10.25:
Password:

Can someone please let me know where I'm going wrong?

Thanks
Tim

I don't think you can have utilities like ssh/scp take in passwd from an
echo on the command line.
I'd also suggest you change your password(s) based on the <removed>
line
above ... from your original email.

if you really want to do something like this, I'd suggest expect as the
scripting language.

What are you trying to do?  Copy your public key out to use it for future
authentication?  Use ssh-copy-id to set it up the first time?  Or look at
the package sshpass.

Don't try to automate your password like this for scp or other
ssh-related apps.  Generate and use a public/private keypair instead and
your script will then be able to connect without prompting for a password.

Well, look at the lines in my script that I'm showing here. That's
exactly
what I'm doing. Copying up my public key so that later in the script (which
I didn't show, no need to I think) is to cat the public key into place and
make sure there are proper permissions etc on the .ssh directory on the
remote machine.

But Eero and other are right.. I'll be much better off using expect to get
this type of work done. It's jut that I'm more familiar with bash so I
thought that there might be a good way to do it with that also.
